The load balancer periodically polls the varnishd's for a static file (lying also at all the backend servers) to check if varnishd is still working. It does that once per second. This completely messes up statistics like hit ratio because that static file is served from cache all the time, so currently our hit ratio is close to 99.9%. I would like to have counted this specific file neither as miss nor hit, but just serve it and ignore it otherwise. It doesn't even need to be logged. haproxy has an option monitor-net where you can specify that it does not need to log requests from that subnet. Does varnish offer a similar option? Or is there some cool VCL snippet I could add? Thanks in advance.
