How to Add Cookies to an HTTP Request

Question:
How do you add explicit cookies to the HTTP header? I understand how to save and re-send cookies, but not how to add new cookies.

Answer:
The AddHeader method can be called to add cookies to an HTTP header.
A Cookie header has this format:

Cookie: name1=value1 [; name2=value2] ...

The values may be enclosed in quotes.
