| Hello Fellow Squid Users, Can you please help? I have been researching this for a long time and cannot find any information on this "what is the $ mean” within StoreID? Below is my failed attempt to make StoreID work correctly. Sorry it's a mess. I have since disabled my customized StoreID patterns because it caused issues. My question is with regard to the $number part of the program. I disabled all the facebook and all my tests because my photos where showing up wrong and it would duplicate itself over everything, I would have to clear the cache and change items and try again below is my failed attempt to get it to work correctly. It did work sometimes however I would get issues the longer it went on for. I decided to stop the trial and testing of it because it was driving me crazy. It is a great puzzle to solve. Does anyone have any tips? I have some Squid text books like the Squid the definitive guide, and The Squid Proxy Server 3.1 guide still nothing really explains StoreID outside of the Squid website. Yes the website comes with a great database that does work, I tested some database items with Ubuntu updates inside of VMs and it worked and reserved them to other machines asking for the same update. So in my quest I thought can I also do this with Facebook… (I do not recommend you try it) or something else, Youtube. This is the Text file I have been testing and it was a failed test outside of Ubuntu updates however I do not use that OS anymore so it is removed I think I had the $ wrong I have no info on what it does some are 1 some are 5 some are doubles $ and another of them: ^https?:\/\/(fbcdn|scontent).*(akamaihd|fbcdn)\.net\/.*\/v\/.*\/(.*\.mp4) http://facebook.squid.internal/$3 ^https?:\/\/fbcdn\-(static|profile)\-a\.akamaihd\.net\/static\-ak\/rsrc\.php\/((?!.*\.(?:js|css|swf)).*) http://facebook.squid.internal/static/$2 ^https?:\/\/(fbcdn|scontent).*(akamaihd|fbcdn)\.net\/(h|s)(profile|photos).*\/(.*\.(png|gif|jpg))(\?.+)? http://facebook.squid.internal/$5 ^https?:\/\/fbstatic\-a\.akamaihd\.net\/rsrc\.php\/((?!.*\.(?:js|css|swf)).*) http://facebook.squid.internal/static/$1 ^http:\/\/.*[steampowered|steamcontent]\.com\/([^?]*) http://steamupdates.squid.internal/$1 ^https?\:\/\/download\.oracle\.com\/((otn\-pub|otn)\/[\d\w]+\/[\d\w]+\/[\w\d\-]+\/[\w\d\-]+\.(exe|dmg|rpm|msi|tar\.(gz|Z)))\? http://java.oracle.otn.ngtech.squid.internal/$1 ^https?\:\/\/([\d\w\-]+)\.oracle\.com\/(([\d\w]+)\/[\d\w]+\/[\d\w]+\/([\d\w\-]+)\/([\d\w]+\/)?[\d\w\-\.\_]+\.(dmg|msi|exe|tar\.gz|tar\.Z))\? http://java.oracle.download.ngtech.squid.internal/$2 ^http:\/\/[^\.]+\.phobos\.apple\.com\/(.*) http://appupdates.apple.squid.internal/$1 ^http:\/\/[^\.]+\.c\.android\.clients\.google\.com\/(.*) http://androidupdates.google.squid.internal/$1 My question here is: What does this $3 mean within the the store id program?

It takes a text file with two tab separated columns. Column 1: Regular _expression_ to match against the URL Column 2: Rewrite rule to generate a Store-ID Eg: ^http:\/\/[^\.]+\.dl\.sourceforge\.net\/(.*) http://dl.sourceforge.net.squid.internal/$1 Rewrite rules are matched in the same order as they appear in the rules file. So for best performance, sort it in order of frequency of occurrence. This program will automatically detect the existence of a concurrency channel-ID and adjust appropriately. It may be used with any value 0 or above for the store_id_children concurrency= parameter. =head1 OPTIONS The only command line parameter this helper takes is the regex rules file name. =head1 AUTHOR This program and documentation was written by I<Alan Mizrahi <alan@xxxxxxxxxxxxxx>> Based on prior work by I<Eliezer Croitoru <eliezer@xxxxxxxxxxxx>> =head1 COPYRIGHT * Copyright (C) 1996-2023 The Squid Software Foundation and contributors * * Squid software is distributed under GPLv2+ license and includes * contributions from numerous individuals and organizations. * Please see the COPYING and CONTRIBUTORS files for details.
