Hello, we have a site running cherokee 1.2.2 behind pound 2.5 (to take care of TLS) on debian squeeze.
The site consists of static files and PHP (5.3.3-7+squeeze1) only. The vhost has 3 rules: - Redirect Non-TLS to TLS - Use FastCGI Backend (php-cgi) for php files - Default: List & Send with I/O-Cache enabled That means, cherokee takes external requests on port 80 only to redirect them to 443 (pound). Pound takes external requests on port 443 and uses localhost:80 to talk to cherokee. Keep-Alive and Chunked Encoding are both enabled (if that matters). The site contains a file.php to take care of special file downloads. After initially switching from nginx to cherokee, we've been running into lots of trouble with that file.php and truncated downloads. Part of that was solved using pound for TLS but there have still been issues with specific files since file.php was piping files through PHP completely. After switching to X-Sendfile, everything looked good. However, we received notice that some downloads are still being truncated every once in a while. We have not been able to pinpoint the cause yet, but we have only seen it happen with IE 8 (other versions could be affected too). file.php produces 4 headers: Content-Type: application/force-download Content-Length: filesize($filepath) Content-Disposition: attachment; filename="$filename" X-Sendfile: $filepath Sniffing the traffic between pound and cherokee revealed that Content-Length is NOT being sent out by cherokee. Thus, the client/browser does NOT know about the total filesize and cannot even detect if the file was completely transferred or not. Also, the transfer is gzipped (Content-Encoding: gzip) and cherokees access.log reports differing sizes for the same file. Could that have to do with gzip? So that leaves three questions: Why are downloads truncated sometimes? Why does cherokee not send Content-Length although it is explicitly given by the PHP backend? Why are access logs reporting differing sizes for the same file? Any ideas and/or suggestions? Thanks in advance Ringo _______________________________________________ Cherokee mailing list [email protected] http://lists.octality.com/listinfo/cherokee
