(C++) Adding Cookies to an HTTP Request

Demonstrates how to add one or more cookies to an HTTP request. For Chilkat HTTP methods that use an HTTP request object, such as SynchronousRequest or PostUrlEncoded, cookies are added by calling the AddHeader method on the request object. For Chilkat HTTP methods that do not use an HTTP request object, such as QuickGetStr, cookies are added by calling AddQuickHeader.

    //  The Cookie header field has this format:
    //  Cookie: name1=value1 [; name2=value2] ...

    //  Build an HTTP POST request:

    request.put_HttpVerb("POST");

    request.AddParam("param1","value1");

    //  To add cookies to any HTTP request sent by a Chilkat HTTP method
    //  that uses an HTTP request object, add the cookies to the
    //  request object by calling AddHeader.

    //  Add two cookies:
    request.AddHeader("Cookie","user=\"mary\"; city=\"Chicago\"");

    //  Send the HTTP POST.
    //  (The cookies are sent as part of the HTTP header.)
