Creating and ACL for Access only through originating domain.

[only1gmose]

We have a server running SSRS, where we provide access for reporting. We have our main site where users login (www.example.com). and we've created a link to our SSRS reporting (www.portalreports.example.com:8080/reports). We want to create an ACL to where the (www.portalreports.example.com:8080/reports) can only be access via the (www.example.com) if someone copies the (www.portalreports.example.com:8080/reports) and tries to send it to someone or paste it in another browser we don't want it to work. So we only want it to work from login in to the orinating domain (www.example.com). Is there a way to do this via ACL or on the ASA.

Not that I'm aware of. Could you just code in an HTTP_REFERER check on the reports webpage to check to make sure it came from www.example.com?
