How do I track a program Internet Request? Like Windows Live Messenger, in order to make a bot that does the same thing. Because I'm making a application that verifies the number of users online, and chat with these people, but I would like to know, where does it connect to do that.
In Web I use the LiveHTTPHeader or FireBug to see where is the page sending GET/Post DATA too and which parameters are being sent. What about desktop applications? how do I do?
You should use a library, for instance in csharp: http://code.google.com/p/msnp-sharp/
Because tracking web request is irrelevant. if you want to make a bot, you should work with an Api.
