We have a service that returns 503 errors with Cache-Control: max-age=X. In
Varnish 2 it was easy to get it to cache and get the appropriate ttl with a
block like this:
sub vcl_fetch {
if (beresp.status == 503) {
set beresp.cacheable = true;
}
}
Now that beresp.cacheable is removed in varnish 3, how do I set beresp.ttl to
the contents of Cache-Control: max-age?
This is the best I've come up with so far, but it doesn't take Age into account
and it's a bit ugly in my opinion:
if (beresp.status == 503 && beresp.http.Cache-Control ~ "max-age") {
set beresp.ttl = std.duration(regsub(beresp.http.Cache-Control,
"^.*max-age=([0-9]+).*$", "\1s"), 1s);
}
Does anyone have a better solution?
