Object Creation

loObject = createobject("CkHttp")

Properties

AbortCurrent
AbortCurrent As Boolean
Introduced in version 9.5.0.58

When set to .T., causes the currently running method to abort. Methods that always finish quickly (i.e.have no length file operations or network communications) are not affected. If no method is running, then this property is automatically reset to .F. when the next method is called. When the abort occurs, this property is reset to .F.. Both synchronous and asynchronous method calls can be aborted. (A synchronous method call could be aborted by setting this property from a separate thread.)

top
Accept
Accept As Character

This property sets the Accept header for all HTTP requests, except those sent by the HttpReq and HttpSReq methods that use headers from an HttpRequest object.

By default, it is set to */*.

Setting this property is the same as calling SetRequestHeader with Accept as the header field name.

The Accept HTTP header is sent by the client (your application) to tell the server which content types (MIME types) it can handle in the response.

For example, the following means only a JSON response is accepted:

Accept: application/json

top
AllowGzip
AllowGzip As Boolean

If .T. then the Accept-Encoding: gzip is automatically added for all HTTP requests, except those made using the HttpReq and HttpSReq methods that use headers from an HttpRequest object.

The default value is .T..

The Accept-Encoding HTTP header is sent by the client to tell the server which compression algorithms it supports for the response body.

Example:

Accept-Encoding: gzip, deflate

This means the client can handle responses compressed with gzip or deflate.

If this property is set to .F., then the Accept-Encoding header is added, but the value is empty, like this:

Accept-Encoding: 

It means the client explicitly does not accept any content codings (no compression, no transformations).

  • An absent Accept-Encoding header means the client will accept any encoding (server chooses, often gzip).
  • An empty Accept-Encoding header means only the “identity” encoding (i.e., uncompressed) is acceptable.

The SetRequestHeader method can be called with Accept-Encoding as the header field name to explicitly set the Accept-Encoding header. Note: Chilkat does not accept Brotli responses. Do not include br in the list of encodings for this header.

The RemoveRequestHeader can be called to explicit omit the Accept-Encoding header field from HTTP requests.

top
AllowHeaderFolding
AllowHeaderFolding As Boolean
Introduced in version 9.5.0.63

When set to .F., MIME header folding is not applied to request headers automatically. By default, this setting is .T.. This property exists for rare instances when a server cannot properly handle folded MIME headers.

MIME header folding allows long header lines to be split across multiple lines for readability.

A folded line begins with whitespace (space or tab), which signals continuation.

Unfolded (single line):

Subject: This is a very long subject line that needs to be wrapped across lines

Folded (wrapped for transport):

Subject: This is a very long subject line
 that needs to be wrapped across lines

When received, the folded version is unfolded back into a single line by removing the CRLF + leading whitespace.

top
AuthSignature
AuthSignature As Character
Introduced in version 9.5.0.89

This property can be set to a JSON string containing the required information to add an HTTP Signature in the following format:

Authorization: Signature
  keyId="my-key-1",
  algorithm="hmac-sha256",
  headers="(request-target) host date",
  signature="Base64OfSignature"

See the linked example below for details.

top
AuthToken
AuthToken As Character
Introduced in version 9.5.0.67

Applications can set this property to the OAuth2 access_token value to be sent in the Authorization: Bearer {access_token} header for all requests. For OAuth1.0a tokens, use the OAuthToken property instead.

Starting from Chilkat v10.1.2, this method can also accept a JSON string containing details needed for automatic OAuth2 access token retrieval via the Client Credentials flow. The JSON must include the client secret, client ID, token endpoint, and scope(s). See the example below for guidance. This feature is compatible with any OAuth2 provider that supports the client credentials flow.

top
AutoAddHostHeader
AutoAddHostHeader As Boolean

When set to .T. (the default), the Host header is automatically added to all requests. The domain for the Host header is taken from the URL passed in a method's arguments.

The Host HTTP header specifies the hostname (and optional port) of the server the client is trying to reach.

Example:

Host: www.example.com

It’s required in HTTP/1.1 so a server can distinguish between multiple sites (virtual hosts) on the same IP address.

top
AwsAccessKey
AwsAccessKey As Character

The AWS Access Key to be used with the Amazon S3 methods listed below.

top
AwsEndpoint
AwsEndpoint As Character

Specify the regional endpoint (domain) for Amazon S3 method calls. The default is s3.amazonaws.com, but you can use any valid Amazon S3 endpoint, such as s3-eu-west-1.amazonaws.com, or endpoints from other S3-API compatible services.

More Information and Examples
top
AwsRegion
AwsRegion As Character
Introduced in version 9.5.0.56

The AWS S3 region (e.g., us-east-1, us-west-2, eu-west-1, eu-central-1) defaults to us-east-1. It is relevant only when the AwsSignatureVersion property is set to 4 and ignored when set to 2.

top
AwsSecretKey
AwsSecretKey As Character

The AWS Secret Key to be used with the Amazon S3 methods listed below.

top
AwsSessionToken
AwsSessionToken As Character
Introduced in version 9.5.0.95

This is the AWS session token for temporary security credentials.

When you call AssumeRole with AWS STS, you get temporary security credentials consisting of:

  • Access key ID
  • Secret access key
  • Session token

The session token is an extra credential that must be included with the access key and secret key when signing requests. It proves the credentials came from STS and are valid for the limited session duration.

In short: The AWS session token is a required component of temporary STS credentials, used alongside the key pair to authenticate API calls.

top
AwsSubResources
AwsSubResources As Character

This property can be used to specify sub-resources to be included in the Amazon S3 methods listed below. For example, set the property to acl&versionId=value to request the acl for a specific version of an object.

In Amazon S3, sub-resources are special query parameters you can append to an S3 object or bucket URL to access or manage specific properties or features beyond the main resource itself.

Examples:

  • Bucket sub-resources: ?logging, ?website, ?lifecycle, ?policy
  • Object sub-resources: ?acl, ?torrent, ?restore, ?tagging

So:

  • Resource = the bucket or object itself (e.g., mybucket/photo.jpg)
  • Sub-resource = a specific aspect or configuration of it, accessed with a query string (e.g., mybucket?logging or photo.jpg?acl).

In short: S3 sub-resources let you operate on metadata/configuration of a bucket or object, not the content itself.

top
BandwidthThrottleDown
BandwidthThrottleDown As Numeric
Introduced in version 9.5.0.49

If set to a non-zero value, this limits the download bandwidth to the specified maximum number of bytes per second. The default value is 0.

top
BandwidthThrottleUp
BandwidthThrottleUp As Numeric
Introduced in version 9.5.0.49

If set to a non-zero value, this property limits the upload bandwidth to the specified maximum number of bytes per second. The default is 0.

top
BasicAuth
BasicAuth As Boolean

To enable HTTP basic authentication, set this property to .T.. The default value is .F..

Then basic authentication is enabled, Chilkat uses the Login and Password properties to include the Authorization: Basic {base64} header in all requests.

HTTP Basic Authentication is a simple authentication scheme where the client sends a username and password encoded in Base64 in the Authorization header.

Example:

Authorization: Basic dXNlcjpwYXNzd29yZA==

Here dXNlcjpwYXNzd29yZA== is the Base64 of user:password.

More Information and Examples
top
ClientIpAddress
ClientIpAddress As Character

A computer can have multiple network interfaces (e.g., Ethernet, Wi-Fi, VPN, virtual adapters). Each interface can have one or more IP addresses (IPv4 and/or IPv6).

If multiple IPs exist (say, 192.168.1.10 on Wi-Fi and 10.0.0.5 on Ethernet), the application can bind explicitly to either one, determining which interface and address the socket will use for communication.

This property can be set to explicitly bind the communications socket to an IP address.

The default value is the empty string, which means the application does not bind to a specific local IP before connecting and the OS network stack automatically picks the default source IP.

More Information and Examples
top
ConnectFailReason
ConnectFailReason As Numeric (read-only)
Introduced in version 9.5.0.56

This property will be set to the status of the last HTTP connection made (or failed to be made) by any HTTP method.

Possible values are:

0 = success

Normal (non-TLS) sockets:
1 = empty hostname
2 = DNS lookup failed
3 = DNS timeout
4 = Aborted by application.
5 = Internal failure.
6 = Connect Timed Out
7 = Connect Rejected (or failed for some other reason)
50 = HTTP proxy authentication failure.
98 = Async operation in progress.
99 = Product is not unlocked.

SSL/TLS:
100 = TLS internal error.
101 = Failed to send client hello.
102 = Unexpected handshake message.
103 = Failed to read server hello.
104 = No server certificate.
105 = Unexpected TLS protocol version.
106 = Server certificate verify failed (the server certificate is expired or the cert's signature verification failed).
107 = Unacceptable TLS protocol version.
108 = App-defined server certificate requirements failure.
109 = Failed to read handshake messages.
110 = Failed to send client certificate handshake message.
111 = Failed to send client key exchange handshake message.
112 = Client certificate's private key not accessible.
113 = Failed to send client cert verify handshake message.
114 = Failed to send change cipher spec handshake message.
115 = Failed to send finished handshake message.
116 = Server's Finished message is invalid.
125 = Peer tried to connect using older SSL 2.0 protocol version.
126 = TLS Pin Set Mismatch.
127 = TLS 1.3 handshake error.

top
ConnectTimeout
ConnectTimeout As Numeric

Determines the maximum time, in seconds, to wait for an HTTP server to accept a TCP connection before timing out. The default value is 30 seconds.

Note: A TLS connection always starts with a normal TCP connection (e.g., client connects to server on port 443). Once TCP is established, the client and server perform a TLS handshake: they exchange cryptographic messages to authenticate, agree on encryption keys, and set up a secure channel.

The ReadTimeout property applies to TLS handshake communications. When establishing a TLS connection, the ConnectTimeout governs the initial TCP connection, followed by the ReadTimeout.

top
CookieDir
CookieDir As Character

Designates a directory path for automatic cookie storage (such as "c:/myCookieDir" or "/Users/example/myCookieDir") when the SaveCookies property is set to .T.. Cookies are saved in XML files, with one file per domain. Alternatively, set the value to memory to cache cookies in memory.

The default value is the empty string, which means cookies are not saved regardless of the SaveCookies setting.

More Information and Examples
top
DebugLogFilePath
DebugLogFilePath As Character

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

More Information and Examples
top
DefaultFreshPeriod
DefaultFreshPeriod As Numeric

Sets the default freshness period (in minutes) for cached documents when the FreshnessAlgorithm property is set to 0. The default value is 10080 (1 week).

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

top
DigestAuth
DigestAuth As Boolean

Setting this property to .T. causes the HTTP component to use digest authentication. The default value is .F..

top
FetchFromCache
FetchFromCache As Boolean

Set to .T. to enable fetching pages from cache whenever possible. The default value is .F.. Only HTTP GET requests are cached. HTTP responses containing Set-Cookie headers are never cached. A page is retrieved from the disk cache if it exists and is deemed fresh by the FreshnessAlgorithm property. If the cached page is stale, the HTTP component will send a revalidate request and update the cache based on the response.

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

More Information and Examples
top
FinalRedirectUrl
FinalRedirectUrl As Character (read-only)

If an HTTP GET was redirected (as indicated by the WasRedirected property), this property will contain the final redirect URL, assuming the FollowRedirects property is .T..

Note: Starting in v9.5.0.49, this property will contain the redirect URL for 301/302 responses even if FollowRedirects is not set to .T..

top
FollowRedirects
FollowRedirects As Boolean

If true, then 301, 302, 303, 307, and 308 redirects are automatically followed when calling QuickGet and QuickGetStr. FollowRedirects is true by default.

top
FreshnessAlgorithm
FreshnessAlgorithm As Numeric

To determine the freshness of a cached HTTP GET response, the freshness algorithm is employed. By default, it uses the LM-factor algorithm, which is activated when the FreshnessAlgorithm is set to 1. The LMFactor property, ranging from 1 to 100, specifies the percentage of the time since the last modification date of the HTML page that the page remains fresh. For instance, if the LMFactor is 50 and the page was last modified 10 days ago, it will expire after 5 days (50% of 10 days). This applies only to HTTP responses without explicit expiration information. If the FreshnessAlgorithm is set to 0, a constant expiry period, defined by the DefaultFreshPeriod property, is applied.

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

top
IgnoreMustRevalidate
IgnoreMustRevalidate As Boolean

If an HTTP response includes the Cache-Control: must-revalidate header, it indicates that the server requires the client to revalidate the page with the server rather than serving it directly from the cache. However, if this property is set to .T., the page will be served directly from the cache without revalidation until it expires. The defautl value of this property is .F..

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

top
IgnoreNoCache
IgnoreNoCache As Boolean

Some HTTP responses include headers indicating the page should not be cached. Chilkat HTTP will follow these instructions unless this property is set to .T.. The default value of this property is .F..

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

top
KeepResponseBody
KeepResponseBody As Boolean
Introduced in version 9.5.0.55

If .T., then the response body, if text, is saved to the LastResponseBody property for all methods that do not return an HttpResponse object. The default value of this property is .F..

top
LastMethodSuccess
LastMethodSuccess As Boolean

Indicates the success or failure of the most recent method call: .T. means success, .F. means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages. Note: This property does not apply to methods that return integer values or to boolean-returning methods where the boolean does not indicate success or failure.

top
LastModDate
LastModDate As Character (read-only)

The value of the Last-Modified header in the last HTTP response received by the HTTP component.

top
LastResponseBody
LastResponseBody As Character (read-only)
Introduced in version 9.5.0.55

The response body of the last HTTP response received by the HTTP component (for methods that do not return an HttpResponse object). The last response body is only saved to this property IF the KeepResponseBody property is set to .T..

top
LastStatusText
LastStatusText As Character (read-only)
Introduced in version 9.5.0.69

The last HTTP status text received by the HTTP component. This only applies to methods that do not return an HTTP response object. For methods that return an HTTP response object, such as SynchronousRequest, the status text is found in the StatusText property of the response object.

top
LMFactor
LMFactor As Numeric

The LMFactor is an integer between 1 and 100 that specifies the percentage of time from an HTTP page's last-modified date to be used as the freshness period. The default is 25. For instance, if a page's last-modified date is 4 weeks ago and LMFactor is set to 25, the page will remain fresh in the cache for 1 week (25% of 4 weeks).

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

top
Login
Login As Character

The HTTP login for pages requiring a login/password. Chilkat HTTP can do Basic, Digest, and NTLM HTTP authentication. (NTLM is also known as SPA (or Windows Integrated Authentication). To use Basic authentication, the BasicAuth property must be set equal to .T.. It is not necessary to set the NtlmAuth or DigestAuth properties beforehand if NTLM or Digest authentication is needed. However, it is most efficient to pre-set these properties when the type of authentication is known in advance.

Important: If NTLM authentication is used, it may be incorrect to set the Login property equal to mydomain\mylogin. Instead, set the LoginDomain property equal to mydomain, and set this property equal to mylogin.

Note: When the Login and Password properties are set, and the type of authentication is specified by setting one of the following properties equal to .T. (BasicAuth, DigestAuth, NtlmAuth), Chilkat will automatically add the Authorization: ... header in the correct format.

top
LoginDomain
LoginDomain As Character

The optional domain name to be used with NTLM / Negotiate authentication.

top
MaxConnections
MaxConnections As Numeric

The maximum number of simultaneous open HTTP connections managed by the HTTP component. The Chilkat HTTP component automatically manages HTTP connections. If the number of open HTTP connections is about to be exceeded, the connection with the least recent activity is automatically closed.

top
MaxFreshPeriod
MaxFreshPeriod As Numeric

Sets a time limit for how long a document can remain fresh in the cache, measured in minutes, with a default value of 525,600 minutes (equivalent to 1 year).

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

top
MaxResponseSize
MaxResponseSize As Numeric

The maximum HTTP response size to be accepted by the calling program. A value of 0 (the default) indicates that there is no maximum value.

top
MaxUrlLen
MaxUrlLen As Numeric

The Http class will automatically fail any URL longer than this length. The default MaxUrlLen is 2000 characters.

top
MimicFireFox
MimicFireFox As Boolean

If set to .T., then the appropriate headers to mimic Mozilla/FireFox are automatically added to requests sent via the QuickGet and QuickGetStr methods.

top
MimicIE

If set to .T., then the appropriate headers to mimic Internet Explorer are automatically added to requests sent via the QuickGet and QuickGetStr methods.

top
MinFreshPeriod
MinFreshPeriod As Numeric

Sets the minimum time a document stays fresh in the cache, with a default of 30 minutes.

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

top
NegotiateAuth
NegotiateAuth As Boolean

Set this property equal to .T. for Negotiate authentication.

Note: The NegotiateAuth property is only available for the Microsoft Windows operating system.

top
NtlmAuth
NtlmAuth As Boolean

Setting this property to .T. causes the HTTP component to use NTLM authentication (also known as IWA -- or Integrated Windows Authentication) when authentication with an HTTP server. The default value is .F..

top
NumCacheLevels
NumCacheLevels As Numeric

This setting determines the directory levels used under each cache root. The default value is 0, meaning cached HTML pages are stored directly in the cache root directory.

  • Level 0: Cached pages are stored in the cache root directory.
  • Level 1: Cached pages go into one of 255 subdirectories (0 to 255) under the cache root.
  • Level 2: Two levels of subdirectories (0-255/0-255) are created under each cache root.

The HTTP class automatically creates these subdirectories as needed. Multiple directory levels help prevent issues caused by having too many files in a single directory.

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

More Information and Examples
top
NumCacheRoots
NumCacheRoots As Numeric (read-only)

Specifies the number of established cache roots used by the HTTP cache to distribute the disk cache across multiple directories. Each cache root is an absolute directory path, set using the AddCacheRoot method.

                oauth_version="1.0"
The information used to compute the OAuth Authorization header is obtained from the other OAuth* properties, such as OAuthConsumerKey, OAuthConsumerSecret, OAuthRealm, etc.

top
OAuthBodyHash
OAuthBodyHash As Boolean
Introduced in version 9.5.0.91

When set to .T., the oauth_body_hash, which contains the SHA-256 hash of the HTTP request body, is automatically included in the OAuth1.0a Authorization header.

For example:

This property is only used when the OAuth1 property equals .T..

top
OAuthRealm
OAuthRealm As Character

The OAuth1.0a realm to be used in the Authorization header.

The OAuth 1.0a realm parameter is an optional, descriptive string in the Authorization header that indicates the protected resources’ scope. It is not required, not included in the signature, and rarely used in real-world APIs. Most modern OAuth 1.0a integrations ignore it completely.

This property is only used when the OAuth1 property equals .T..

top
OAuthSigMethod
OAuthSigMethod As Character

Specify the oauth_signature_method parameter in the OAuth 1.0a Authorization header. The default method is HMAC-SHA1, but it can be set to HMAC-SHA256, RSA-SHA1, or RSA-SHA256. For RSA methods, provide an RSA private key using the SetOAuthRsaKey method.

This property is only used when the OAuth1 property equals .T..

Note that RSA-SHA256 is supported from Chilkat v9.5.0.56 onwards.

top
OAuthToken
OAuthToken As Character

The value to be used for the oauth_token parameter in the OAuth1.0a Authorization header.

This property is only used when the OAuth1 property equals .T..

top
Password
Password As Character

The HTTP password for pages requiring a login/password. Chilkat HTTP can do Basic, Digest, and NTLM HTTP authentication. (NTLM is also known as SPA (or Windows Integrated Authentication). To use Basic authentication, the BasicAuth property must be set equal to .T.. It is not necessary to set the NtlmAuth or DigestAuth properties beforehand if NTLM or Digest authentication is needed. However, it is most efficient to pre-set these properties when the type of authentication is known in advance.

Note: When the Login and Password properties are set, and the type of authentication is specified by setting one of the following properties equal to .T. (BasicAuth, DigestAuth, NtlmAuth), Chilkat will automatically add the Authorization: ... header in the correct format.

top
PreferIpv6
PreferIpv6 As Boolean

If .T., then use IPv6 over IPv4 when both are supported for a particular domain. The default value of this property is .F., which will choose IPv4 over IPv6.

top
ProxyAuthMethod
ProxyAuthMethod As Character

Set this to basic if you know in advance that Basic authentication is to be used for the HTTP proxy. Otherwise leave this property unset. Note: It is not necessary to set this property. The HTTP component will automatically handle proxy authentication for any of the supported authentication methods: NTLM, Digest, or Basic. Setting this property equal to basic prevents the 407 response which is automatically handled internal to Chilkat and never seen by your application.

Note: If NTLM authentication does not succeed, set the Global.DefaultNtlmVersion property equal to 1 and then retry.

top
ProxyDirectTls
ProxyDirectTls As Boolean
Introduced in version 9.5.0.83

Set to .T. if the proxy server expects a direct TLS connection. (This is where the initial connection to the HTTP proxy server is TLS. See Squid Direct TLS Connection. The default value of this property is .F..

top
ProxyDomain
ProxyDomain As Character

The domain name of a proxy host if an HTTP proxy is used. This can also be set to an IP address.

top

If an HTTP proxy is used and it requires authentication, this property specifies the HTTP proxy login.

top
ProxyLoginDomain
ProxyLoginDomain As Character

The NTLM authentication domain (optional) if NTLM authentication is used.

top
ProxyPassword
ProxyPassword As Character

If an HTTP proxy is used and it requires authentication, this property specifies the HTTP proxy password.

top
ProxyPort
ProxyPort As Numeric

The port number of a proxy server if an HTTP proxy is used.

top
ReadTimeout
ReadTimeout As Numeric

The amount of time in seconds to wait before timing out when reading from an HTTP server. The ReadTimeout is the amount of time that needs to elapse while no additional data is forthcoming. During a long download, if the data stream halts for more than this amount, it will timeout. Otherwise, there is no limit on the length of time for the entire download.

The default value is 60 seconds. Note: Prior to v9.5.0.76, the default was 20 seconds.

top
ReceivedCertReq
ReceivedCertReq As Boolean (read-only)
Introduced in version 9.5.0.92

Indicates whether the last HTTPS connection received a TLS CertificateRequest handshake message indicating that the server may require a client certificate.

top
RedirectVerb
RedirectVerb As Character

Indicates the HTTP verb, such as GET, POST, PUT, etc. to be used for a redirect when the FollowRedirects property is set to .T.. The default value of this property is GET. This will produce the same behavior as a web browser (such as FireFox). If this property is set to the empty string, then it will cause the same verb as the original HTTP request to be used.

Note: Prior to version 9.5.0.44, the default value of this property was the empty string.

top
RequiredContentType
RequiredContentType As Character

If set, then any HTTP response to any POST or GET, including downloads, will be rejected if the content-type in the response header does not match this setting. If the content-type does not match, only the header of the HTTP response is read, the connection to the HTTP server is closed, and the remainder of the response is never read.

This property is empty (zero-length string) by default.

Some typical content-types are text/html, text/xml, image/gif, image/jpeg, application/zip, application/msword, application/pdf, etc.

top
RequireHostnameMatch
RequireHostnameMatch As Boolean
Introduced in version 11.0.0

If .T., then the hostname/domain in the URL must match at least one of the entries in the server certificate's SAN. A SAN (Subject Alternative Name) field in an SSL/TLS certificate contains a list of additional domain names, subdomains, IP addresses, or other identifiers that the certificate is valid for.

In actuality, it is the SNI hostname in the TLS handshake that must match a SAN entry. By default, Chilkat uses the hostname from the URL as the SNI hostname. An application can explicitly set the SNI hostname via the SniHostname property, which would be typical if connecting via an IP address. See the example below.

The default value is .F..

top
RequireSslCertVerify
RequireSslCertVerify As Boolean

If .T., then the HTTP client will verify the server's SSL certificate. The certificate is expired, or if the cert's signature is invalid, the connection is not allowed. The default value of this property is .F..

top
SaveCookies
SaveCookies As Boolean

If this property is .T., cookies are automatically persisted to XML files in the directory specified by the CookiesDir property (or in memory if CookieDir = memory). Both CookiesDir and SaveCookies must be set for cookies to be persisted.

More Information and Examples
top
SendBufferSize
SendBufferSize As Numeric

The buffer size to be used with the underlying TCP/IP socket for sending. The default value is 65535.

top
SendCookies
SendCookies As Boolean

More Information and Examples
top
SessionLogFilename
SessionLogFilename As Character

Enables file-based session logging. If set to a filename (or relative/absolute filepath), then the exact HTTP requests and responses are logged to a file. The file is created if it does not already exist, otherwise it is appended.

More Information and Examples
top
SniHostname
SniHostname As Character
Introduced in version 9.5.0.82

Sets the SNI hostname for the TLS ClientHello. This property is usually necessary only when the domain is specified by an IP address and an SNI hostname is required. By default Chilkat uses the hostname in the URL for the SNI hostname in the TLS ClientHello extension automatically.

More Information and Examples
top
SocksHostname
SocksHostname As Character

The SOCKS4/SOCKS5 hostname or IPv4 address (in dotted decimal notation). This property is only used if the SocksVersion property is set to 4 or 5).

top
SocksPassword
SocksPassword As Character

The SOCKS5 password (if required). The SOCKS4 protocol does not include the use of a password, so this does not apply to SOCKS4.

top
SocksPort
SocksPort As Numeric

The SOCKS4/SOCKS5 proxy port. The default value is 1080. This property only applies if a SOCKS proxy is used (if the SocksVersion property is set to 4 or 5).

top
SocksUsername
SocksUsername As Character

The SOCKS4/SOCKS5 proxy username. This property is only used if the SocksVersion property is set to 4 or 5).

top
SocksVersion
SocksVersion As Numeric

SocksVersion May be set to one of the following integer values:

0 - No SOCKS proxy is used. This is the default.
4 - Connect via a SOCKS4 proxy.
5 - Connect via a SOCKS5 proxy.

top
SoRcvBuf
SoRcvBuf As Numeric

Sets the receive buffer size socket option. Normally, this property should be left unchanged. The default value is 4194304.

This property can be increased if download performance seems slow. It is recommended to be a multiple of 4096.

top
SoSndBuf
SoSndBuf As Numeric

Sets the send buffer size socket option. Normally, this property should be left unchanged. The default value is 262144.

This property can be increased if upload performance seems slow. It is recommended to be a multiple of 4096. Testing with sizes such as 512K and 1MB is reasonable.

top
SslAllowedCiphers
SslAllowedCiphers As Character
Introduced in version 9.5.0.48

Provides a means for setting a list of ciphers that are allowed for SSL/TLS connections. The default (empty string) indicates that all implemented ciphers are possible. The TLS ciphers supported in Chilkat v9.5.0.55 and later are:

TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256
TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256
TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384
TLS_DHE_RSA_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_AES_256_CBC_SHA256
TLS_RSA_WITH_AES_256_GCM_SHA384
TLS_RSA_WITH_AES_256_CBC_SHA
TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256
TLS_DHE_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA256
TLS_RSA_WITH_AES_128_GCM_SHA256
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA
TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_ECDHE_RSA_WITH_RC4_128_SHA
TLS_RSA_WITH_RC4_128_SHA
TLS_RSA_WITH_RC4_128_MD5
TLS_DHE_RSA_WITH_DES_CBC_SHA
TLS_RSA_WITH_DES_CBC_SHA
To restrict SSL/TLS connections to one or more specific ciphers, set this property to a comma-separated list of ciphers such as TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384. The order should be in terms of preference, with the preferred algorithms listed first. (Note that the client cannot specifically choose the algorithm is picked because it is the server that chooses. The client simply provides the server with a list from which to choose.)

The property can also disallow connections with servers having certificates with RSA keys less than a certain size. By default, server certificates having RSA keys of 512 bits or greater are allowed. Add the keyword rsa1024 to disallow connections with servers having keys smaller than 1024 bits. Add the keyword rsa2048 to disallow connections with servers having keys smaller than 2048 bits.

Note: Prior to Chilkat v9.5.0.55, it was not possible to explicitly list allowed cipher suites. The deprecated means for indicating allowed ciphers was both incomplete and unprecise. For example, the following keywords could be listed to allow matching ciphers: aes256-cbc, aes128-cbc, 3des-cbc, and rc4. These keywords will still be recognized, but programs should be updated to explicitly list the allowed ciphers.

secure-renegotiation: Starting in Chilkat v9.5.0.55, the keyword secure-renegotiation may be added to require that all renegotions be done securely (as per RFC 5746).

best-practices: Starting in Chilkat v9.5.0.55, this property may be set to the single keyword best-practices. This will allow ciphers based on the current best practices. As new versions of Chilkat are released, the best practices may change. Changes will be noted here. The current best practices are:

  • If the server uses an RSA key, it must be 1024 bits or greater.
  • All renegotations must be secure renegotiations.
  • All ciphers using RC4, DES, or 3DES are disallowed.

Example: The following string would restrict to 2 specific cipher suites, require RSA keys to be 1024 bits or greater, and require secure renegotiations: TLS_DHE_RSA_WITH_AES_256_CBC_SHA256, TLS_RSA_WITH_AES_256_CBC_SHA, rsa1024, secure-renegotiation

top
SslProtocol
SslProtocol As Character
Introduced in version 9.5.0.46

Selects the SSL/TLS protocol version to be used for connections. Possible values are:

default
TLS 1.3
TLS 1.2
TLS 1.1
TLS 1.0
SSL 3.0
TLS 1.3 or higher
TLS 1.2 or higher
TLS 1.1 or higher
TLS 1.0 or higher
The default value is default which allows for the protocol to be selected dynamically at runtime based on the requirements of the server. Choosing an exact protocol will cause the connection to fail unless that exact protocol is negotiated. It is better to choose X or higher than an exact protocol. The default is effectively SSL 3.0 or higher.

top
StreamResponseBodyPath
StreamResponseBodyPath As Character
Introduced in version 9.5.0.49

Allows for the HTTP response body to be streamed directly into a file. If this property is set, then any method returning an HTTP response object will stream the response body directly to the file path specified. The HTTP response object will still contain the response header. (This property is useful when the HTTP response is too large to fit into memory.)

top
TlsCipherSuite
TlsCipherSuite As Character (read-only)
Introduced in version 9.5.0.49

Contains the current or last negotiated TLS cipher suite. If no TLS connection has yet to be established, or if a connection as attempted and failed, then this will be empty. A sample cipher suite string looks like this: TLS_DHE_RSA_WITH_AES_256_CBC_SHA256.

top
TlsPinSet
TlsPinSet As Character
Introduced in version 9.5.0.55

Specifies a set of pins for Public Key Pinning for TLS connections. This property lists the expected SPKI fingerprints for the server certificates. If the server's certificate (sent during the TLS handshake) does not match any of the SPKI fingerprints, then the TLS handshake is aborted and the connection fails. The format of this string property is as follows:

hash_algorithm, encoding, SPKI_fingerprint_1, SPKI_fingerprint_2, ...
For example, the following string specifies a single sha256 base64-encoded SPKI fingerprint:
"sha256, base64, lKg1SIqyhPSK19tlPbjl8s02yChsVTDklQpkMCHvsTE="
This example specifies two SPKI fingerprints:
"sha256, base64, 4t37LpnGmrMEAG8HEz9yIrnvJV2euVRwCLb9EH5WZyI=, 68b0G5iqMvWVWvUCjMuhLEyekM5729PadtnU5tdXZKs="
Any of the following hash algorithms are allowed:.sha1, sha256, sha384, sha512, md2, md5, haval, ripemd128, ripemd160,ripemd256, or ripemd320.

The following encodings are allowed: base64, hex, and any of the encodings indicated in the link below.

top
TlsVersion
TlsVersion As Character (read-only)
Introduced in version 9.5.0.49

Contains the current or last negotiated TLS protocol version. If no TLS connection has yet to be established, or if a connection as attempted and failed, then this will be empty. Possible values are SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3.

top
UncommonOptions
UncommonOptions As Character

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string and should typically remain empty. Can be set to a list of the following comma separated keywords:

  • QuickDisconnect - Introduced in v9.5.0.77. In the call to CloseAllConnections, do not disconnect cleanly. Instead just disconnect as quickly as possible.
  • ProtectFromVpn - Introduced in v9.5.0.80. On Android systems, will bypass any VPN that may be installed or active.
  • TlsNoClientRootCert - Introduced in v9.5.0.82. Will exclude root CA certs from being included in the client certificate chain that is sent to the server for client-side authentication. This must be set prior to calling SetSslClientCert.
  • AllowEmptyHeaders - Introduced in v9.5.0.82. If present, an empty value string passed to SetHeaderField will cause the header to be added with an empty value. Otherwise, for historical purposes and backward compatibility, the header field is removed when an empty value string is passed.
  • AnsiLogin - Introduced in v9.5.0.87. For HTTP basic authentication, the login and password is sent using the utf-8 byte representation. Some servers expect the ANSI byte representation (typically Windows-1252). Use this keyword to send the login/password using ANSI.

top
UpdateCache
UpdateCache As Boolean

Set this property to .T. to automatically updated with HTTP GET request responses. Only HTTP GET requests are cached. HTTP responses containing Set-Cookie headers are never cached. The default value is .F..

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

More Information and Examples
top
UseIEProxy
UseIEProxy As Boolean

If .T., the proxy address/port used by Internet Explorer will also be used by Chilkat HTTP. Note: This property only pays attention to the proxy address and port, and does not pay attention to additional information such as IE proxy server exceptions.

top
UserAgent
UserAgent As Character

This property sets the User-Agent header for all HTTP requests, except those sent by the HttpReq and HttpSReq methods that use headers from an HttpRequest object.

By default, it is set to an empty string, meaning no User-Agent header is included.

Setting this property is the same as calling SetRequestHeader with User-Agent as the header field name.

The User-Agent HTTP header is sent by the client to identify the software making the request (browser, app, library, bot, etc.).

Example:

MyApp/1.1

Note: Some web servers reject requests that do not include a User-Agent.

More Information and Examples
top
VerboseLogging
VerboseLogging As Boolean

If set to .T., then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is .F.. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
Version As Character (read-only)

Version of the component/library, such as "10.1.0"

More Information and Examples
top
WasRedirected
WasRedirected As Boolean (read-only)

Indicates whether the last HTTP request was redirected (i.e. the redirect was automatically followed). If FollowRedirects is .F. and the response status code is 301, 302, 303, 307, or 308, then this property will remain .F. but the FinalRedirectUrl will contain the redirect URL that was not automatically followed.

top

Methods

AddCacheRoot
AddCacheRoot(dir As Character)

Disk caching operates similarly to browser caching of web pages, but it focuses on downloading web pages rather than handling HTTP requests to a REST API.

To activate disk caching, invoke the method at least once. Use the AddCacheRoot method and provide a file path (e.g., D:\MyHttpCache\) to set the root directory. To distribute the cache over multiple directories, call AddCacheRoot multiple times with different directory paths.

HTTP GET web page caching properties and methods include: NumCacheRoots, NumCacheLevels, AddCacheRoot, FetchFromCache, UpdateCache, MinFreshPeriod, MaxFreshPeriod, FreshnessAlgorithm, DefaultFreshPeriod, LMFactor, IgnoreMustRevalidate, IgnoreNoCache, and LastFromCache.

More Information and Examples
top
ClearUrlVars
ClearUrlVars()
Introduced in version 9.5.0.67

Removes all URL variable values previously set by SetUrlVar .

top
CloseAllConnections
CloseAllConnections() As Boolean

Closes all remaining open HTTP connections.

An HTTP object can hold up to 10 connections. If a server response lacks a Connection: Close header, the connection stays open and may be reused for subsequent requests to the same host. Connections are identified by their IP address or domain name as specified in the URL. Once the limit of 10 connections is reached, the least recently used connection will be closed to open a new one.

Returns .T. for success, .F. for failure.

More Information and Examples
top

CreateTimestampRequest
CreateTimestampRequest(hashAlg As Character, hashVal As Character, reqPolicyOid As Character, addNonce As Boolean, reqTsaCert As Boolean, timestampToken As CkBinData) As Boolean
Introduced in version 9.5.0.75

Creates an RFC 3161 time-stamp request and returns the binary request token in timestampToken. The hashAlg can be sha1, sha256, sha384, sha512, or md5, The hashVal is the base64 hash of the data to be timestamped. The optional reqPolicyOid is the requested policy OID in a format such as 1.3.6.1.4.1.47272.1.2. The addNonce indicates whether to auto-generate and include a nonce in the request. It may be .T. or .F.. The reqTsaCert determines whether or not to request the TSA's certificate (.T. = Yes, .F. = No).

Note: After creating the timestamp request, send it to the server using HttpBd with a POST request and a Content-Type of application/timestamp-query. Use VerifyTimestampReply to analyze and verify the timestamp reply. See the examples linked below.

Returns .T. for success, .F. for failure.

top
DnsCacheClear
DnsCacheClear()
Introduced in version 9.5.0.38

This function clears the Chilkat in-memory DNS cache, which stores hostname-to-IP address mappings to avoid repeated DNS lookups.

Note:

  • The DNS cache is shared across all Chilkat objects, so clearing it will impact all such objects.
  • Chilkat's DNS caching respects the TTL (time to live) of DNS records. If the TTL has expired since the initial lookup, Chilkat will perform a new DNS query and update the cache with the latest IP address.

SetSslCertRequirement(reqName As Character, reqValue As Character)
Introduced in version 9.5.0.84

Enforces a requirement on the server's certificate. The reqName can be one of the following:

  • SubjectDN
  • SubjectCN
  • IssuerDN
  • IssuerCN
  • SAN

The reqName specifies the part of the certificate, and the reqValue is the value that it must match exactly or with a wildcard (*), for example "*.example.com". If the server's certificate does not match, the SSL / TLS connection is aborted.

Returns .T. for success, .F. for failure.

SetSslClientCert
SetSslClientCert(cert As CkCert) As Boolean

Facilitates the use of a client-side certificate for a TLS connection, enabling mutual authentication. In a standard TLS connection, the server alone presents a certificate during the handshake to verify its identity. With mutual TLS (mTLS), the client also presents a trusted certificate, allowing the server to authenticate the client's identity. This process enhances security by adding a layer of verification beyond just usernames, passwords, or tokens.

Returns .T. for success, .F. for failure.

top
SetSslClientCertPem

SharePointOnlineAuth
SharePointOnlineAuth(siteUrl As Character, username As Character, password As CkSecureString, extraInfo As CkJsonObject) As Boolean
Introduced in version 9.5.0.73

This method authenticates with SharePoint Online and if successful, sets a cookie which is used for all following SharePoint HTTP requests. Before using this method, ensure you configure the CookieDir property to either memory or a specific directory path to store the authentication cookie, which will then be automatically used for subsequent HTTP requests.

Using this method automatically sets the SaveCookies and SendCookies properties to .T., as these settings are necessary for SharePoint Online authentication.

To use the method, provide the following arguments:

  • siteUrl: The URL, e.g., https://yourdomain.sharepoint.com/
  • username: An email address, e.g., username@yourdomain.com
  • password: The Sharepoint password.
  • extraInfo: Can be an empty JSON object. Reserved for additional information if needed in the future.

Returns .T. for success, .F. for failure.

VerifyTimestampReply
VerifyTimestampReply(timestampReply As CkBinData, tsaCert As CkCert) As Numeric
Introduced in version 9.5.0.75

Verifies a timestamp reply received from a timestamp authority (TSA). Returns the following possible integer values:

  • -1: The timestampReply does not contain a valid timestamp reply.
  • -2: The timestampReply is a valid timestamp reply, but failed verification using the public key of the tsaCert.
  • 0: Granted and verified.
  • 1: Granted and verified, with mods (see RFC 3161)
  • 2: Rejected.
  • 3: Waiting.
  • 4: Revocation Warning
  • 5: Revocation Notification

If the timestamp reply (timestampReply) is known to be from a trusted source, then the tsaCert may be empty. If tsaCert is empty (never loaded with a certificate), then the verification will use the certificate embedded in the timestamp reply.

The CreateTimestampRequest method is used to create a timestamp request.
