storeid_file_rewrite — File based Store-ID helper for Squid


storeid_file_rewrite filepath


This program acts as a store_id helper program, rewriting URLs passed by Squid into storage-ids that can be used to achieve better caching for websites that use different URLs for the same content.

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 concurrecy channel-ID and adjust appropriately. It may be used with any value 0 or above for the store_id_children concurrency= parameter.


The only command line parameter this helper takes is the regex rules file name.
