Hi

I run a website that has authentication "provided" by another site -
basically we supply a username, password and destination page to the
other site and, once the user is authenticated, they get put on the
page on our site they originally requested (this is a client
requirement so there's no changing it).

This had been working fine until XP SP2. We've been using

Request.ServerVariables("HTTP_REFERER")

to check the referer, but now IE (only on XP SP2) returns an empty
string. Other browsers (NS, FF) return the referer. I created just to
show the referer string to confirm this and indeed the page was blank.
Funny thing is if I refresh that page, the original referer shows up!
Ayway, I now need some alternative way to find out the referring
domain that will accommodate IE XP SP2.

Any ideas?

Thanks
