The plugin was complete and working for 2.1.4, but there have been a number of API changes since then. I'll work on getting it built against 2.1.6 and mail a link to the code here.
Currently the plugin takes a list of regex/replacement pairs which is apples to all URLs, and changes the URL that they're cached under. Hopefully that should cover most people's use cases. A couple of examples: http://example.com/(.+)\?.* http://example.com/$1 http://server[1-4].example.com/(.*)?id=([0-9]+) http://test.ATSINTERNAL/$1_$2 this works with any part of the URL, including the query string, and was inspired by the store_url feature in a past version of squid. 2011/3/21 ChangCheng <[email protected]>: > Hi, Mark > I am working on this plugin as well. but i still haven't find better way to > solve this problem. could you give some suggestion for this problem if > possible? > Thanks lots > >> From: [email protected] >> Date: Mon, 21 Mar 2011 13:52:35 -0400 >> Subject: Re: how to cache object with different urls (with question mark) >> just once? >> To: [email protected] >> >> I've been working on a plugin that does just that, but it hasn't yet >> been updated to work with anything past 2.1.4 (It's on my todo list). >> However, I seem to remember somebody else also working on this also >> which may be further along.
