How to check as to where from the user came to a page

[abadona]

Hello, every one:

I have two files running on one site one of them is ASPX and other ASP.

The ASPX file authenticates users against AD. Then Response.Redire ct sends username as query sting to ASP script.

My question is how can I check within ASP (VB script) where did the request came from, and only honour requests that came from ASPX page.

in server variable there is HTTP_REFER object which shows from which page request come from
