I'm setting up Varnish Cache 3.0.4 and Apache 2.22 on the same Xubuntu server, with Varnish accepting connections on port 80, and Apache listening on port 81. The intention is to cache .html files in Varnish, but at the moment, all requests are passed through to the server.
I set up /usr/local/etc/varnish/default.vcl as follows:
backend default { .host = "127.0.0.1"; .port = "81"; } sub vcl_recv { # Do not cache following pages (edit as needed for your configuration). if (!( req.url ~ "wp-(login|admin|comments-post)" )) { return (pass); } # Drop the cookies for everything else unset req.http.cookie; # Try a cache-lookup return (hash); } sub vcl_backend_response { # Below will cache the page for one week.(1s = 1 sec, 1d = 1 day) set beresp.ttl = 1w; } I use this script to start Varnish:
#!/bin/sh ulimit -n 10240 ulimit -l 16384 /usr/local/sbin/varnishd -f /usr/local/etc/varnish/default.vcl \ -a :80 \ -s malloc,16M -l 8m,1m,+ -u varnishd I enabled mod headers and added this code to /etc/apache2.conf:
<FilesMatch "\.html$"> Header set Cache-control "public, max-age=9200" </FilesMatch> The HTTP headers from a GET request are as follows:
HTTP/1.1 200 OK Server: Apache/2.2.22 (Ubuntu) Last-Modified: Thu, 10 Oct 2013 13:50:01 GMT ETag: "e719-1884-4e8634739cce1" Accept-Ranges: bytes Vary: Accept-Encoding Cache-control: public, max-age=9200 Content-Type: text/html Date: Fri, 11 Oct 2013 17:54:29 GMT X-Varnish: 21561442 Age: 0 Via: 1.1 varnish Connection: close Accept-Ranges: bytes I ran a test using this command on another PC:
seige -d1 -c800 -t1 http://192.168.0.7/specs.html I looked at the ouput of varnishstat which appears to show that all requests where passed to the backend. The values for MAIN.s_req and MAIN.s_pass where both 126003. Can anyone suggest why Varnish isn't caching any data?
