Dynamic Content Caching using Lighty + mod_magnet + lua

September 17th, 2007 by GadElKareem

*Updated 11 Jan 2007 to include luazlib, fix lighty config file and add zlib decoding to cache.lua for older browsers
Since I read the documentations for mod_cml, I was very excited to use this module since caching using PHP running as FastCGI is not helping much during server peak load. However, mod_cml was replaced by mod_magnet which is more flexible and gives more control over request handling in Lighttpd. This Article will focus on caching your PHP scripts using Lua and mod_magnet under Lighttpd, #more-42" class="more-link"> more.. »
