RE: [squid-users] Corruption problem of download files from squid

I have the same problem with that PDF on 2.6S4 on fedora 6. It won't even begin to download. File or website problems?

Subject: [squid-users] Corruption problem of download files from squid

Hi,

I am using Squid STABLE4 on FC3 with common configurations in squid.conf :-

http_port 8080
acl QUERY urlpath_regex cgi-bin \? \.asp asp .asp \.jsp jsp .jsp \.dll .dll servlet Servlet .do no_cache deny QUERY maximum_object_size 716800 KB ....
refresh_pattern -i windowsupdate.com/.*\.(cab|exe|psf) 4320 100% 43200 reload-into-ims refresh_pattern -i download.microsoft.com/.*\.(cab|exe|psf) 4320 100% 43200 reload-into-ims ....

The squid proxy server works well most of the time. However, when I tried to download a PDF from the following :-

http://www.citizenwatch.com/COA/English/settingsresults.asp?caliber=7871

I found that the PDF file was corrupted that the file size was less than it should be. The complete file size was 82,831 bytes when downloaded directly from Internet bypassing squid proxy, but the download file via squid proxy was only 78,784 bytes. Moreover, the result file size varied every time the file was downloaded, e.g. the file sizes were 31536 bytes, 79320 bytes etc.

I tried with IE6 SP2 and Firefox 1.5.0.7/2.0, and Squid SABLE5, and the same problem remained. I hope someone could advise what went wrong, and how to fix the problem. The following are the access, cache and store logs.

Thanks a lot.
