Hi Antony, Correct, the kid contacts the parent that is getting a 504 and replies the same to the kid. That's why I suspect the parent tries to download by itself instead replying to the kid it does not have the object so the kid should do a fresh download from internet. examples: TCP_MISS/504 708 GET http://w.sharethis.com/button/buttons.js - CD_SIBLING_HIT/x.x.x.x TCP_MISS/504 708 GET http://www.googletagmanager.com/gtm.js?id=GTM-NNVXD6 - CD_SIBLING_HIT/x.x.x.x TCP_MISS/504 478 GET http://dl4.offercdn.com/2613/styleVideo.css - HIER_NONE/- TCP_MISS/504 708 GET http://www.indianrail.gov.in/seat_Avail.html - CD_SIBLING_HIT/x.x.x.x etc... The kid receives these answers and does nothing more, the result is the browser (client) does not have all the objects for a correct page... Sometimes, the page is blank because a js script, css, etc... is missing. There are 2 squid, sibling each of them. Squid1 (10.1.1.1): cache_peer 10.1.1.2 sibling 8182 8183 proxy-only no-tproxy Squid2 (10.1.1.2): cache_peer 10.1.1.1 sibling 8182 8183 proxy-only no-tproxy Both are in tproxy (settings from the Squid wiki), ICP is enabled with each squid. if you need more details, feel free to ask Bye Fred -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/TCP-MISS-504-in-cache-peer-tp4671944p4671957.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
