While working with the newly fixed output compression plugin, one of the devs in my team discovered that it breaks with send_file(). So if you are using send_file() in your application you must get the fixed file I''ve put at: http://devblog.famundo.com/output_compression.rb. The change is actually in checking for the Content-Disposition header added by send_file(). See the full writeup in my blog: http://devblog.famundo.com/articles/2006/04/03/one-more-fix-in-output_compression. Enjoy! Guy. -- Family management on rails: http://www.famundo.com - coming soon!
