How to block URLs when client is behind a Proxy?

Hi everyone,

Is it in some way possible, using HIPS/IPS 8, to block certain URLs for clients that is behind a proxy server? Or do I have to use something like Web Filtering for Endpoint?

You would be far better served doing this with Web Filtering for Endpoint (Site Advisor). In an emergency you can block domain names using Host IPS (the firewall itself) but that is not the right tool for URL management.

So you think that it would work even tho the clients traffic go through a web proxy? I mean, the clients cant do any DNS queries to Internet themself.

HIPS does not block URLs (http://www.domain.com/subdomain/files).  HIPS can block by Domain name or by FQDN.  If I recall correctly, both of these require non-proxy communication, since the local system must perform the DNS resolution.  If an application is proxying, then the local system does not perform the DNS lookup locally; the proxy server does the DNS lookup.

Thanks Kary, that was my though also. What products of McAfee is the best suited one for this task?

Web Filtering for Endpoint, SiteAdvisor Enterprise v3.5? Im not "read in" on those two in their versions.
