Question

I have one desktop application which was implemented in C#. This app uploads file to remote web server, I want to grab all http requests sent from this application. Is it possible to grab?

There is a great HTTP debugger called Fiddler (http://www.fiddler2.com), well worth investing a bit of time to learn.
