Hi, We're running Squid in reverse proxy as an http accelerator. When our back end web server that generates the uncached content has problems and becomes unresponsive, so does our front-end Squid server. is there a way that we can have Squid ignore this and continue to serve cached content to users when a certain timeout has passed when contacting the back end apache server? it would be helpful in two ways, one, vistiors accessing cached content won't experience the interruption, and two, connections to the back end server won't pile up, adding to the problem. any suggestions? thanks, travis
