Hi list, why can't i download the a file like : http://mirror.switch.ch/ftp/mirror/fedora/linux/core/3/i386/iso/FC3-i386-DVD.iso with a size of 2.3 GB, while there is no problem with downloading another file from the same directory like this : http://mirror.switch.ch/ftp/mirror/fedora/linux/core/3/i386/iso/FC3-i386-disc1.iso ? The latter one is a normal CD-ISO Image and the first is a DVD-ISO Image the DVD is much bigger than the CD. I firts thought of a filesystem limitation, so i wrote a no_cache directive, which did not help. I asume there is a limitation on the filesize. I found an Article covering a similar topic (Filesize) but with FTP and not HTTP. How can i let my users downloading such large files without bypassing squid ? When i route the request through Viruswall directly instead of Squid, it works fine. I just have no clue on how i can route request for large files directly to the viruswall instead of the squid. Is there a patch or a compile option for letting squid support large files. Configuration : OS : Fedora Core 3 Linux Squid : 2.5.STABLE6 The Trendmicro Viruswall is configured as a parent to the squid. Any help is gratefully appreciated. Cheers, Philipp
