Thanks for reply . I assumed the community at different scales from little isp to large ISPs may have common domains like those i highlighted so they may have same issue as mine . So i ignored common parts . One of problems with redbot is it shows timeout for big files like http://gs2.ww.prod.dl.playstation.net/gs2/appkgo/prod/CUSA00900_00/2/f_2df8e321f37e2f5ea3930f6af4e9571144916013ee38893d881890b454b5fed6/f/UP9000-CUSA00900_00-BLOODBORNE000000_4.pkg?downloadId=00000187&du=000000000000018700e2291bda0f868f&country=us&downloadType=ob&q=aa2cd9c8d1f359feb843ae4a6c99cfcdb6569ca9cc60ad6d28b6f8de3b5fac23&threadId=0&serverIpAddr=23.57.69.81&r=00000027 http://gs2.ww.prod.dl.playstation.net/gs2/ppkgo/prod/CUSA07557_00/25/f_053bab8c9dec6fbc68a0bd9fc58793285ae350ccf7dadacb35b5840228a9d802/f/EP4001-CUSA07557_00-F12017EMASTER000-A0113-V0100_0.pkg?downloadId=00000059&du=000000000000005900e22977e62f91a2&downloadType=ob&product=0183&serverIpAddr=8.248.5.254&r=00000032 I assumed anyone with few thousand of users may have same problem and maybe they like to share for example their refresh_pattern or storeid to solve my problem . You better know that playstation is everywhere playstation ;) Here is part of storeid_db file ^http:\/\/.*\.sonycoment\.loris-e\.llnwd\.net\/(.*?\.pkg) http://playstation.net.squidinternal/$1 ^http:\/\/.*\.playstation\.net\/(.*?\.pkg) http://playstation.net.squidinternal/$1 Almost all of the playstation huge downloads are with 206 code but it will download the file from start to end , if i remember correctly in this situation squid will correctly cache the file . -- Sent from: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-Users-f1019091.html _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
