Hi, The server side has an IP blacklist, and the IP is retrieved from the incoming HTTP header. Because I need to test the blacklist, I need to insert client IP to the HTTP request. The client is developed with WinHTTP, c++. According to MSDN, the WINHTTP_OPTION_CONNECTION_INFO is not surported by windows server 2003, so I cannot use it. Any other way to do that? Thanks, Meal
