Hey Omid, StoreID is not the only thing which can affect a HIT or a MISS. A nice tool which was written to understand the subject is RedBot at: https://redbot.org/ >From a simple inspection of the file it seems that it should get hit but, why are you using StoreID for this object? Also why are you using: refresh_pattern -i ^http:\/\/[a-zA-Z0-9\-\_\.]+\.squid\.internal\/.* 10080 95% 86400 override-lastmod override-expire reload-into-ims ignore-reload ignore-must-revalidate ignore-no-store ignore-private ?? You would only need this for the specific case which the hostname is "dynamic". This url seems by default cache friendly and only if you have enough details on their cdn network you should try to use StoreID. Something that may help you is the next log format settings: logformat cache_headers %ts.%03tu %6tr %>a %Ss/%03>Hs %<st %rm %ru %[un %Sh/%<a %mt Q-CC: "%{Cache-Control}>h" "%{Cache-Control}>ha" Q-P: "%{Pragma}>h" "%{Pragma}>ha" REP-CC: "%{Cache-Control}<h" REP-EXP: "%{Expires}<h" VARY: "%{Vary}<h" %>eui access_log daemon:/var/log/squid/access.log cache_headers Try to see how the requests for these looks like in the logs.
