Users in the company I work for are denied access to webmail via websense running on a web proxy.  My question is this.  If a business user was granted access to webmail - for example gmail - and downloaded or uploaded an attachment to or from gmail to his desktop within the corporate lan... would that attachment be subject to the scanning and filtering present on the proxy server?

I am not sure wheter attachments can be scanned when users browse through SSL (gmail is SSL enabled), as it is encrypted between both parties.

But can easily tested by downloading a test-virus through:
http://www.eicar.org/anti_virus_test_file.htm 

They host the testvirus both on HTTP and HTTPS. See what's happening.

If the user uses SSL gmail, you won't be able to know what he is doing, otherwise, I am in doubt as well, as the files download are usually redirected from the http header.
If you want full control you need to have something like Websense Gateway, and not Websense Security suite.
