Can anyone elaborate on the > long default keep-alive of squid. Apache is a web server with a priority focus on delivering all responses to multiple related objects in a 5-10 second period then releasing resources for other users. So that it can servie all Internet users in existence if necessary. Squid is a proxy designed and tuned to cope with a wide range of old and slow networks. Providing the clients with what it asked for regardless of how long the users browser stays idle. It is just a default, you can change it if you like. Reverse proxies will serve better with shorter timeouts like Apache. ISP or corporate proxies will serve better with longer ones like the default (or even longer). > > 2.

The idle_timeout, request_timeout and lifetime_timeout are just upper limits on how long the client masy stay in any one of those transaction states. Amos
