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 have tried the telnet codes to access the OWA folder and the
scripts come back very fast and the images take for every. Not sure
what is going wrong.
It's 258 KB after compression and not being cached. Size may have
something to do with it if the scripts are much smaller.
