Currently I have two pages:

The first page contains an input form, and the 2nd page generates an excel document. The input form's button posts to this 2nd page.

What I'd like to do is add a second button which also posts to the 2nd page; however, I'll need requests created from this new button to act differently, which brings me to my question:

Is there a way I can tell, from the 2nd page, which button was pressed to submit the request?

The main reason I'm asking is I'd like to re-use the 2nd page's logic in parsing the information from the first page if possible; I'd rather not have to copy it to a new page and have the new button post to that.

Thanks!
