How can I check for the site that transferred to my site?

[mb224]

I have a .NET site say (

http://www.SiteA.com)....

and another department (

http://www.SiteB.com)

have their own site .... (classic ASP)

Once a user has already been authenticated from SiteB .. I want them to be tansferred later to me site SiteA. Normally I already have authentication for SiteA if one is logging in directly to SiteA ........ but if one is coming in from SiteB .. I want to skip having them to log-in again ... so I cretaed a sub folder on SiteA that allows anonymous access .... but I want to restrict it only to when you are being transferred from SiteB ...

Is it the httpcontext object .. or something like that .. that I can check for the site that transferred to my site ... or how do I check?

Thanks

You can use the HTTP_REFERER ServerVariable
