TinyMCE Ruby on Rails GZip Compressor
UPDATE: I've refactored this into a Plugin.
They already have solved this problem, however it takes some serverside magic. I did some searching and didn't find any solutions for this in Ruby. After putting it off for awhile, I finally decided to try it myself.
I have only tested this on my application, so I would appreciate it if some other people would try it out. Once I get some feedback, I'll release it as a plugin.
To set it up, download this controller and put it into your controllers directory. After that you need to add the following lines to your routes.rb.
Have fun, and leave feedback here in the comments.
