In my scenrio (squid 3.5.23) I have several clients which download content. Now I want to achieve two things: if one client has already downloaded the content the second client requesting the same content should take it from the squid cache. But: when this content resource on the internet is changing the squid should not give a HIT but a MISS and refresh the content the next time a client is requesting it. It is not clear to me how to achieve this behaviour. The application (server on internet) sends headers like this: cache-control: public, max-age=0 last-modified: Thu, 12 Sep 2019 07:30:56 GMT etag: W/"6699e3-16d2461dba1" So far I could only achieve HITs using refresh_pattern with min value > 0. refresh_pattern . 30 20% 1440 override-expire But also this configuration is not exactly what I want. Now even if the content of a resource on the internet is changing I get HITs for 30 min. -- Sent from: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-Users-f1019091.html _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
