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.

What are the reply headers for each of these tests? Amos
