Pointing SquidGuard Squid proxy for realtime url reputation or category check

Question

I am trying to use Sophos Intelix for url category checking or for filtering through squid proxy. Also caching a result locally on the proxy (for a specific duration) until url is checked again.  I am using Intelix for some time in other custom apps and it works well. I am looking for some help with setting up Sophos Intelix integration with squid. Any help to point me in the right direction is appreciated.
