Newbie: Submit a request

Apologies for this newbie question, but I don't even know what to search for.

What I want to do is create a aspx page with a text box and a search button. When you click the search button, I want to create a web request that searches a particular Yahoo group. When the Yahoo response comes back, I will need to parse, display some stuff to my user, then search again until I reach the beginning of the messages.

Can anyone point me in the right direction?

Thanks,
Mike

Check out how the search strings are created in yahoo group searches, and model your search string similar to that.

That's what I plan on doing, but I don't know the proper mechanism to use on my server. Would I just use a regular tcp connection? Or is there some helper class?

Thanks,
Mike
