I don't think the subject makes much sense but this is what I need to know:

In the web page at www.m-w.com there's a place to look up for words in the Collegiate Dictionary. Given a word, I need to know what's the returned web page when I press the "Look it up" button, so I can download the page.

If someone could explain me how I can generaly know the returned url in these kind of forms, I would apreciate very much.
