I deployed varnish on a webserver that also runs PHP to serve larger files of up to about 1GB. NOTE, I am using the stock varnish shipped with Debian 5, which is varnish version 1.1.2.
After running this setup for a while, I got some reports of constantly interrupting downloads. After some poking around, I realised that downloads of were being interrupted if they took more that 10 minutes. Here's the output from a couple of tests with Varnish: $ time wget -t 1 --header "Host: hostname" http://server:6081/download.php?args=here ... 2009-10-09 12:31:35 (303 KB/s) - Connection closed at byte 186251297. Giving up. real 10m9.089s user 0m4.030s sys 0m11.061s $ time wget -t 1 --header "Host: hostname" http://server:6081/download.php?args=here ... 2009-10-09 12:11:55 (314 KB/s) - Connection closed at byte 192727409. Giving up. real 10m8.255s user 0m3.296s sys 0m10.937s Testing the webserver directly, it works fine. Is there a time limit like this in newer versions of varnish? Is there a workaround I can use? It seems "pass"ing these requests doesn't help, but "pipe"ing them appears to help. Is there a better solution than hardcoding "pipe"s of all requests that could take more than 10 minutes? By the way, I also noticed that even though varnish times out and cuts the connection, varnishncsa logs the full size of the original file, not the amount of data actually transferred.
