Hi, I am using squid 2.6.12 on FreeBSD 5.3-STABLE and 6.2-STABLE. One cache server is configured on the LAN, it forwards requests to 2 parent caches which are in 2 different DMZs (2 lines to 2 different ISP). I compiled squid with cache digest enabled. The parent cache configuration lines: cache_peer 10.28.55.30 parent 3128 3130 cache_peer 172.16.11.2 parent 3128 3130 The caches work ok. The problem is when a client requests a page where a cookie is set. When all the pages are served using the same parent cache it works correctly. When the parent cache changes I get an error message that the cookie is not valid (it is coming from another IP). It does not matter if I am using any options on the cache_peer configuration line (I used round-robin and sourcehash). Am I missing something? What should I configure for cache_peer in mentioned scenario? I tried to search the problem solution in the FAQ and on google but without success. Any help appreciated. Thanks. Regards, lk
