From: des Date: Tue, 8 Jan 2008 10:37:07 +0000 (+0000) Subject: Remove files which confuse users who mistake them for documentation (see #77). X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b24fd3b71dbaaff79baac646a93cc60f59a4fa1e;p=varnish Remove files which confuse users who mistake them for documentation (see #77). There may be a case for resurrecting syntax.txt, but only if it is fixed to reflect what was actually implemented as opposed to what was proposed a year ago. git-svn-id: svn+ssh://projects.linpro.no/svn/varnish/trunk@2334 d4fa192b-c00b-0410-8231-f00ffab90ce4 --- diff --git a/varnish-cache/lib/libvcl/sample.vcl b/varnish-cache/lib/libvcl/sample.vcl deleted file mode 100644 index 24bc4789..00000000 --- a/varnish-cache/lib/libvcl/sample.vcl +++ /dev/null @@ -1,109 +0,0 @@ - -acl rfc1918 { - 10.0.0.0/8; - 172.16.0.0/12; - 192.168.0.0/16; -} - -sub request_policy { - - if (client.ip == 10.1.2.3) { - no_cache; - finish; - } - - if (client.ip ~ rfc1918) { - no_cache; - finish; - } - - if (req.url.host ~ "cnn.no$") { - rewrite "cnn.no$" "vg.no"; - } - - if (req.url.path ~ "cgi-bin") { - no_cache; - } - - if (req.useragent ~ "spider") { - no_new_cache; - } - -# comment - - if (backend.response_time <= 0.8s) { - set req.ttlfactor = 1.5; - } elseif (backend.response_time > 1.5s) { - set req.ttlfactor = 2.0; - } elseif (backend.response_time > 2.5m) { - set req.ttlfactor = 5.0; - } - - /* - * the program contains no references to - * maxage, s-maxage and expires, so the - * default handling (RFC2616) applies - */ -} - -backend vg { - set backend.ip = 10.0.0.100; - set backend.timeout = 4s; - set backend.bandwidth = 2000Mb/s; -} - -backend chat { - set backend.ip = 10.0.0.4; - set backend.timeout = 4s; - set backend.bandwidth = 2000Mb/s; -} - -sub bail { - error 404 "Bailing out"; - finish; -} - -sub fetch_policy { - - if (!req.url.host ~ "/vg.no$/") { - set req.backend = vg; - } else { - /* XXX: specify 404 page url ?
