特定の URL (主に XML 出力) を 5 ~ 10 秒間キャッシュするための Varnish セットアップがあります。DCの人たちはそれをセットアップして設定ファイルを作成しましたが、残念ながらうまくいきません。
構成を確認して、問題の特定に役立てていただければ幸いです。
これが私のdefault.vclです
backend default {
.host = "127.0.0.1";
.port = "80";
}
sub vcl_recv {
if (req.restarts == 0) {
if (req.http.x-forwarded-for) {
set req.http.X-Forwarded-For =
req.http.X-Forwarded-For + ", " + client.ip;
} else {
set req.http.X-Forwarded-For = client.ip;
}
}
if (req.request != "GET" &&
req.request != "HEAD" &&
req.request != "PUT" &&
req.request != "POST" &&
req.request != "TRACE" &&
req.request != "OPTIONS" &&
req.request != "DELETE") {
/* Non-RFC2616 or CONNECT which is weird. */
return (pipe);
}
if (req.request != "GET" && req.request != "HEAD") {
/* We only deal with GET and HEAD by default */
return (pass);
}
if (req.http.Authorization || req.http.Cookie) {
/* Not cacheable by default */
return (pass);
}
if(req.http.host == "foo.example1.com"){
if(req.url ~ "^/somedir\?somevar=anothervar&andanother=.*"){
return (lookup);
}
}else if(req.http.host == "bar.example2.com"){
if(req.url ~ "^/foo/bar\?somevar=anothervar&andanother=.*"){
return (lookup);
}
} else {
return (pass);
}
# Currently not reached.
return (lookup);
}
sub vcl_pipe {
# Note that only the first request to the backend will have
# X-Forwarded-For set. If you use X-Forwarded-For and want to
# have it set for all requests, make sure to have:
# set bereq.http.connection = "close";
# here. It is not set by default as it might break some broken web
# applications, like IIS with NTLM authentication.
return (pipe);
}
sub vcl_hash {
hash_data(req.url);
if (req.http.host) {
hash_data(req.http.host);
} else {
hash_data(server.ip);
}
return (hash);
}
sub vcl_miss {
return (fetch);
}
sub vcl_fetch {
if (beresp.ttl <= 0s ||
beresp.http.Set-Cookie ||
beresp.http.Vary == "*") {
/*
* Mark as "Hit-For-Pass" for the next 2 minutes
*/
set beresp.ttl = 120 s;
return (hit_for_pass);
}
set beresp.ttl = 5 s;
return (deliver);
}
そして、localhostからURLを呼び出そうとしたときのログ出力は次のとおり
curl --verbose --header 'Host: foo.example1.com' "http://127.0.0.1:6081/somedir?somevar=anothervar&andanother=123456"
です。
