Using latest varnish from FreeBSD ports (version 1.1.2), is the following VCL the "correct" solution to support browser shift-reloads to get fresh content and actually update the cache?
sub vcl_hit { if (req.http.Cache-Control ~ "no-cache") { set obj.ttl = 0s; pass; } } As far as I understood vcl(7), this means: 1. fetch the object from cache (implicit in the fact that we're inside vcl_hit) 2. set ttl to 0s, expiring it (so next requests will fetch new content) 3. pass to backend (so *this* request see new content) Does this do what I expect it to do? Is there a way to avoid hitting the backend twice? Is there a way to do that in vcl_recv? (I guess not, since there's no "obj" object available yet, there) I guess I could use purge_url(...), except I have virtual hosts and it wants a regexp and req.url could contain some special char (could it?). -- Lapo Luchini - http://lapo.it/ _______________________________________________ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc
