I don't mean to be smart here but the feature page says: http://wiki.squid-cache.org/Features/CollapsedForwarding "To remedy this situation this patch adds a new tuning knob to squid.conf, making Squid delay further requests while a cache revalidation or cache miss is being resolved. This sacrifices general proxy latency in favor for accelerator performance and thus should not be enabled unless you are running an accelerator." So is collapsed forwarding generally a bad idea for a forward proxy? Gavin
