Re: [squid-users] Squid 3.1 reverse proxy to OWA on IIS7

Hi

Okay - sorry I am just using our website as a test - it is on the same
server as the exchange box and is reverse proxied. Browse the site and you
will see what I mean (how slow it is). Something is going on causing the
images to be sent really slowly. www.optimalprofit.com is the website and
www.optimalprofit.com/owa is the exchange domain. The exchange login page
should be really fast - it take about 4 min to load. If I browse to the
site internally it is really fast.

I am kind of clucking at straws as to what it wrong. Text comes down fast
and images are really slow. SQUID worked a treat with version 2.6, but 2.7,
3.0 and 3.1 all make the reverse proxy really slow.

Many thanks

Gordon

:) I hope not. That is the initial request.

It's 258 KB after compression and not being cached. Size may have
something to do with it if the scripts are much smaller.
