(Visual FoxPro) 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.

*  Any string unlocks the component for the 1st 30-days.
lnSuccess = loHttp.UnlockComponent("Anything for 30-day trial")
IF (lnSuccess <> 1) THEN
    ? loHttp.LastErrorText
    QUIT
ENDIF

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

*  Build an HTTP POST request:
loRequest = CreateObject('Chilkat.HttpRequest')
loRequest.SetFromUrl("http://www.chilkatsoft.com/echoPost.asp")
loRequest.HttpVerb = "POST"

loRequest.AddParam("param1","value1")
loRequest.AddParam("param2","value2")

*  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:
loRequest.AddHeader("Cookie",[user="mary"; city="Chicago"])

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

lnSsl = 0
loResponse = loHttp.SynchronousRequest(lcDomain,lnPort,lnSsl,loRequest)
IF (loResponse = NULL ) THEN
    ? loHttp.LastErrorText
    QUIT
ENDIF

*  Display the HTML body of the response.
IF (loResponse.StatusCode = 200) THEN
    *  Show the last HTTP request header sent, which should include
    *  our cookies...
    ? loHttp.LastHeader

*  Some Chilkat HTTP methods do not use an HTTP request object.
*  For these methods, such as for QuickGetStr, cookies (or any HTTP request header)
*  are added by calling AddQuickHeader.
