问题:

How do I programatically get internet traffic from a web site in C# or C++?

I mean, how can this be done without opening up a browser or a broswer control?

Additionally, there is some sort of plugin to a browser in IE and others where you can watch the communication from a browser to a server and back. Does anyone know about this?

you can check fiddler.

Look into cURL for C++ http://curlpp.org/ or if you want more low-level communication processing check socket programming and winsock. You'll connect to a server on a port and send a GET request, the server will respond with the HTML code if the page is an HTML, etc.

You will have to have some basic HTTP protocol knowledge though. http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol

Use the WebClient.DownloadString() or DownloadStringAsync() with the address of the web site.

Fiddler can be used to watch the browser communication

You can use System.Net.HttpWebRequest, which lets you send http get and http post requests.
