In case a client has already downloaded the content and I request the content again without deleting the local cache (this would be the scenario "same client") in this case I see a 304 HEAD request which is sent out to the server (no new download from the server). Probably this works due to the etag and/or last-modified headers so it can be sorted out whether the content is still fresh or not. But this does not work when the client has an empty cache or not downloaded this resource before. The desired behaviour would be that in this case the squid compares the resource on the server (internet side) with the resouce from its own cache in order to decide whether the content is still fresh or not. Yes - I can allow squid to ask the origin server whether the content is still the same. Probably my problem is that I don't know how to do that. -- 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
