Hi Amos, Yep, i did not modify the TTL transaction. Here, it seems the parent (sibling mode) tries to do the request itself but faces an error (504 gateway timeout), it should answer to the kid it does not have the object (TCP_MISS) then the parent should download the object from internet. With this error, i suspect the kid accepts the "error" and does nothing more, replying to the browser (user) something like "sorry, the object is missing". How can i force the kid to download the object from internet when the parent replies a such answer ? bye Fred -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/TCP-MISS-504-in-cache-peer-tp4671944p4671955.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
