The script I used can be found at http://apaste.info/OPHa and I've verified that it works well for compressing text (I compressed a 50kb html output from a Lua script down to a 5kb chunked message with 4 separate chunks due to calling r:flush() in the script) The documentation for these new filters can be temporarily found at http://www.humbedooh.com/mod_lua.html.en#modifying_buckets while I polish it off for final committing (I have a bad habit of committing stuff, then making 10 new revisions later on ;) ). I just need to finish off some final adjustments, and I'll be committing the Lua filter support to the trunk for review and nagging. With regards, Daniel.
