Slow loading specific web page

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??

I removed everything from my blocking list.

No change whatsoever :(

I tried messing around with the remote UTM - no joy.

I loads at blank page to this point , then just hangning for a looooong time..

I do have to clear webbrowser cache every time to replicate.

My bet is still that its the referrer links that takes the time.

Nothing in the log on fullreqtime is alarming and dns also looks fine.

Will keep one playing around with is as I have time and follow the thread, but no golden solution at the moment.
