Thank you. This option helped a lot. But varnish delivers still 503 errors when the backend is completely down (no route to host, connection refused). Is there a way to handle such situations too?

I want the varnish server to send old cached objects if the backend is down (marked unhealthy). I have tested various grace configurations but nothing worked, because grace takes only effect if the backend is slow, but not if it's down. So is there a way (maybe in vcl_error)? Yes. There is a way. http://www.varnish-cache.org/docs/trunk/tutorial/handling_misbehaving_se rvers.html#saint-mode -- Per Buer, Varnish Software Phone: +47 21 98 92 61 / Mobile: +47 958 39 117 / skype: per.buer
