Which Hyperlink Clicked

I have a web page with a frameset and many links to other pages. Each hyperlink links to a disclaimer page which has a continue button.

I want to capture which hyperlink was clicked on and add it's value to a session key so that the second form knows where to go next.

The problem is that hyperlinks don't have a click event. I could use a link button but .NET won't allow me to add a link button unless it is between form tags and it won't allow me to add form tags to the page that contains the frameset.

Any help would be appreciated.

you can capture the referer url from the second form if that's any good?
Request.UrlReferer

I'd get away from using frames with asp.net pages it i were you.
