Well it's pretty simple, I have used squd 4.0.13 with default settings and the rules you provided ie: squid.conf: store_id_program /usr/lib64/squid/storeid_file_rewrite /etc/squid/storeid-rules store_id_children 40 startup=10 idle=5 concurrency=0 store_id_access allow GET store_id_access deny all /etc/squid/storeid-rules: ^http:\/\/igcdn-.*\.akamaihd\.net/hphotos-ak-.*/(t5.*?)(?:\?|$) http://instagramcdn.squid.internal/$1 But I am not sure how you decided on the StoreID structure. I am pretty sure you can replace the ".*" with a much more accurate rule such as in: ^http:\/\/igcdn-(photos|videos)-([a-z]+)-a\.akamaihd\.net/hphotos-ak-([a-z0-9]+)/(t5[\.\-\_\/a-z0-9]+?)(?:\?|$) http://instagramcdn.squid.internal/$4 Eliezer ---- Eliezer Croitoru Linux System Administrator Mobile: +972-5-28704261 Email: eliezer@xxxxxxxxxxxx -----Original Message----- From: squid-users [mailto:squid-users-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Omid Kosari Sent: Saturday, August 20, 2016 4:41 PM To: squid-users@xxxxxxxxxxxxxxxxxxxxx Subject: Re: Yet another store_id question HIT MISS I have also tested with several browsers, PCs etc . Also i have disabled every refresh pattern except default squid rules as like as yours . Same result .
