Hello,
How can I serve an old object during the fetch of an expired object or max
out connection?
I¹ve configured the grace period in both the vcl_recv as the vcl_fetch.
I even tried to use the saint mode to give me back an ³old² cached object.
Can somebody give me help in this matter?
sub vcl_recv {
# Purge through http
if (req.request == "PURGE") {
if (!client.ip ~ purge) {
error 405 "Not allowed.";
}
ban("req.url ~ " + req.url );
error 200 "Purged.";
}
# Unset all cookies available
if (req.http.cookie) {
unset req.http.cookie;
}
if (req.request != "GET" && req.request != "HEAD") {
/* We only deal with GET and HEAD by default */
return (pass);
}
# Adding Grace period in case backend lags
set req.grace = 3d;
return (lookup);
}
....
sub vcl_fetch {
set beresp.grace = 4d;
set beresp.saintmode = 50s;
set beresp.ttl = 30s;
return (deliver);
}
