Adding Cookies to an HTTP Request

See more HTTP Examples

Demonstrates how to add one or more cookies to an HTTP request. Tcl

load ./chilkat.dll

set success 0

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

set http [new_CkHttp]

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

# Build an HTTP POST request:
set req [new_CkHttpRequest]

CkHttpRequest_SetFromUrl $req "http://www.chilkatsoft.com/echoPost.asp"
CkHttpRequest_put_HttpVerb $req "POST"

CkHttpRequest_AddParam $req "param1" "value1"
CkHttpRequest_AddParam $req "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:
CkHttpRequest_AddHeader $req "Cookie" "user=\"mary\"; city=\"Chicago\""

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