According to my previous emails i have created this topic to summerize my need . Squid has peer config as follow acl wu dstdom_regex \.download\.windowsupdate\.com$ \.download\.microsoft\.com$ acl wu-rejects dstdom_regex stats acl GET method GET cache_peer 1.1.1.14 parent 8080 0 proxy-only no-tproxy no-digest no-query no-netdb-exchange name=ms1 cache_peer_access ms1 allow GET wu !wu-rejects cache_peer_access ms1 deny all never_direct allow GET wu !wu-rejects never_direct deny all The peer software is a web service from http://squid-web-proxy-cache.1019090.n4.nabble.com/Windows-Updates-a-Caching-Stub-zone-A-windows-updates-store-td4678454.html So far so good . the problem begins here . Currently we have exclude the cache hits (based on TOS value) from our customers reserved bandwidth . For example you have 150Mbps internet link from our company and we have limitation for you on our QOS routers . But we have excluded cache hits from your 150M and you may have more than that if you are downloading from our cache hits . The peer software is a web service and is not aware of hit/miss or TOS/DSCP . So i should to a trick with help of squid . Squid (or even iptables, linux , etc ) which is aware of which contents goes to/comes from the peer should do a trick to mark those content with DSCP and send them to routers . Router see that dscp and exclude it from users limitation .
