Hi I recently moved to squid-3.5.11-1.el6.x86_64 on centos 6.7. from the centos 3.1 i think ? This what I had originall #cache_peer gsdmz1.xy.com sibling 3128 3130 proxy-only #cache_peer alcdmz1.xy.com sibling 3128 3130 proxy-only I had a shared config between the 2 server gsdmz1 and alcdmz1. I would uncomment 1 or the other depending. during my upgrade I coped the gsdmz1 squid config over to alcdmz1 but forgot to uncomment the cache_peer alcdmz1.xy.com sibling 3128 3130 proxy-only so alcdmz1 was talking to itself at times. using this as my test wget -d http://www.smh.com.au/business/markets-live/markets-live-investors-take-stock-20151201-gld1lu.html -O /dev/null and setting http_proxy to either alc or gsdmz1 I would get a 504 error. wget -d http://www.smh.com.au/business/markets-live/markets-live-investors-take-stock-20151201-gld1lu.html -O /dev/null Setting --output-document (outputdocument) to /dev/null DEBUG output created by Wget 1.12 on linux-gnu. --2015-12-02 16:35:34-- http://www.smh.com.au/business/markets-live/markets-live-investors-take-stock-20151201-gld1lu.html Resolving alcdmz1... 10.3.2.111 Caching alcdmz1 => 10.3.2.111 Connecting to alcdmz1|10.3.2.111|:3128... connected.

I changed the line to be cache_peer gsdmz1.xy.com sibling 3128 3130 proxy-only standby=50 on the alcdmz1 box and cache_peer alcdmz1.xy.com sibling 3128 3130 proxy-only standby=50 on the gsdmz1 box but this still gave me 504 errors ? I tried to force a new version through both proxies by using wget with no-cache option. But that didn't help. So what went wrong, how can I flush out the stale 504. What is the best way to setup the 2 proxies to talk to each other before going out to the internet. the proxies run on a pacemaker cluster. I have 2 vip's setup as the proxy addresses, in normal conditions these address are setup 1 on each server. whilst working on a server I can move the vip and not affect any one. But I would like to take benefit of each others cache, whats the best setup for cache_peer in this setup. Neither server is closer to the internet. thanks A _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
