Usually. If netdb/icmp has been enabled squid will keep records of response times and go to whichever of peer/web responds fastest. thinking fastest available service is usually best to use. Check your access.log for info on which is being selected for each request. > Then my question is, > 1) which server will query to the internet for the page which is not in > the cache ie ".net" dedicated server or the main proxy1 server? Under only cache_peer_domain, maybe both. Use 'never_direct' to force requests to go via peers. > 2) The new page will be written to the which cache, proxy1 or > proxy2/proxy3 'proxy-only' prevents caching at proxy1 if request came from peer. If request came from web DIRECT then it can be cached at proxy1 and used later. Amos
