[squid-users] Squid cutting off download of files and media issues

Hello all.

I've been having trouble figuring this out so. Thought I'd ask the experts!

Using Squid 2.7 with no ACL's configured to block media or file extensions for download. When users try to download a .PDF for example; the download will start and then hang about halfway through. After hanging for a minute or so the download box will disappear, when the file is checked as you might guess it is incomplete. On occasion I can just click on the file to download and it will complete successfully. More times than not though it will just never work and I have to bypass the proxy to download the file. I have similar issues with flash and other types of video content. As an example: I can go to CNN or Youtube and click on a video file, the file will start to play and then just stop.. Hanging as long as I leave the page open. As a test I've left the page up all day before and sometimes it will just start playing hours later, sometimes it never restarts..

Another problem I've noticed that may be related; this hang seems to happen even on a regular web page such as google.com. I launch the browser and go to google, the page loads but the browser is unresponsive (progress bar sticks about ¾ of the way across) 30 seconds to a minute later the progress bar hits 100% and the page and browser are responsive. I have noticed that during a page hang like this if I am logged into the squid box (Debian Lenny) and I issue a "rndc flush" command the progress bar completes to 100% and the page is immediately responsive.

Any ideas?
