How to authenticate SOAP Requests using HTTP Cookies?
Doing POST and GET requests using HTTP cookies is pretty straightforward. When you register for a service or operation, the system will create a cookie on your computer. Any POST or GET request you place later on should automatically forward the cookie to the our servers. If you delete your cookie or want to add the cookie on another machine, you can easily recreate it by logon to our website using the same email address that you had registered with us.
