Slow Website through Cisco ASA 5510

I have a Cisco ASA 5510 with CSC-SSM (Content Scanning) which has been working great / without a problem for 2 years. We are now experiencing a problem with accessing one particular web server on the Internet, regardless of the site hosted on that server.

We can access the sites, but each page load is taking 2-5 minutes rather than the seconds I'd expect. I've confirmed that outside the firewall and on the same T1 circuit we can access the site without an issue.

I can see the server is Windows and we're hitting ASPX pages, but there doesn't appear to be anything wierd that would explain the slow load time. The pages are very non-busy, and load in literally 1-2 seconds when not through the ASA. Logs / monitoring do not show anything blocked that I've been able to see...

Does anyone have any insight?

The CSC-SSM does URL filtering, and the website(s) in question were newly developed - and not yet classified by Trend Micro. ... This led to the CSC-SSM querying Trend Micro for every hit on the site, delaying every page load.

Tell the CSC-SSM to not filter these particular URLs, and problem is solved.

Of course, should tell Trend to classify those sites too.....
