HELP! -- previous page in VB and ASP 3.0

Hello all,

I'm writing you because I have a question for you all: how can I capture the
previous page from an ASP file?

I need to add the URL (with parameters if possible) of the previous page to
a table in SQL Server.

For example: the page that captures the info is anydomain.com/asppage.asp
and if the previous page in the browser history is
otherdomain.com/otherpage.asp, I need to be able to capture that information

If possible, of course...

Thanks in advance for your help and prompt response,
SB-R
