I wish to retrieve the contents of a webpage which requires a cookie to be set in the header of its request. Unfortunately, I can't seem to find a simple way to add the cookie to the header of the request. The Http::Cookies add_cookie_header method seems to require that the cookie/value pair already be stored in a file of unknown format. Any help on how I can add a simple cookie/value pair to the header of a request without file involement would be greatly appreciated. (something like &add_cookie($request, "username" => "Joe").
