What about a learning mechanism . For example ObjectX is at urlA , urlB , urlC . It is no problem if squid downloads ObjectX from all of them for ONE time but after that it should delete it from cache storage and serve all of them from one file . And then squid should never download them again until they changed ( based on mechanisms which currently using to check that an object should redownload or not ) Also it would be more powerful if squid could learn some relation between urlA , urlB , urlC and if ObjectY requested from one of them , then squid GUESS the same behavior . I know i am dreaming Utopia but discussion is better than silence about it . -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Automatic-StoreID-tp4665140p4665174.html Sent from the Squid - Users mailing list archive at Nabble.com.
