The version from rubylane works flawlessly for us at www.bets4all.com. The only thing we had to patch (as we provide our site in different languages) was a call to NsConnEncodeForOutput for german and spanish special characters. It's in production now for several weeks and we are compressing our main page from up to 200K to less then 20K without hitting the server.
It would be nice if someone could check in a version at sourceforge. Wolfgang
