Slow loading specific web page

IliasTsoukalis

Hi there,

I have a weird problem with loading time on a specific site (http://www.mednet.gr).

The site makes a php GET call for a gzipped css file (http://www.mednet.gr/application/css.php?request=application/themes/mednet/theme.css&c=46) which takes about a minute to complete.

The weird thing is that I get this delay only through Sophos! Not with a direct connection or an obsolete TMG Proxy server that i tried.

I bypassed any checks on the site and used the browser developer tools to verify that I get no error on loading.

Bypass content scanning is enabled (if that makes any difference).

Any ideas??

    Was able to replicate on a remote UTM 120...

     

    Seems it is all of the external referenced content that is taking for ever to get fetched and dragged thru the filter ( fonts, css references, google stuff etc etc )

    Only difference I can see between the remote and the SG230 here is a regex block list I put into a block web adds policy.

    Will have to test some more to be sure though.

     

     

    The list contain ( delim is space )
