HTTPS filtering with Cisco ASA

Hi there,

I've setup Websense Webfilter paired with a Cisco ASA 5520 (8.03). I've set up filtering rules for HTTP and HTTPS on the ASA to pass the traffic to the Websense machine. HTTP filtering works fine and as expected but HTTPS does not. A site that is blocked when accessed via HTTP isn't blocked when accessed via HTTPS. If I run "Test filtering" it says that it is/was blocked. What could be wrong?

HTTP and HTTP is set up the same way and I've read and reread the docs, searched the KB and forums. Still no go. Any tips?

Thanks.
