I'm using squid version 3.1.19, and I want to be able to serve stale pages to the browser, so I modify squid.conf as follows. Everything is pretty much the same as default with *acl my_machine src <ip> http_access allow my_machine* and *refresh_pattern ^http: 600000 100% 700000 override-expire override-lastmod reload-into-ims ignore-reload ignore-no-cache ignore-private ignore-auth* Then, I tested it using squidclient. *squidclient http://stackoverflow.com/* However, it always missed giving me this respond every time (except date and last-modified are different).
