.NET Web browser component that allow you to capture the GET and POST data

I'd like to develop an .NET application, where you navigate in a website and the app records the GET and POST data you send to the server, so later on you can reproduce it programatically.

I've been taking a look on the WinForm's WebBrowse开发者_开发问答r component but I see no way to get the POST data I'm sending.

Do you know of any component (even not free) that allow you to do that?

Try FiddlerCore:

FiddlerCore allows you to integrate HTTP/HTTPS traffic viewing and modification capabilities into your .NET application

Alternatively, you could bypass making the application and just use Fiddler.
