I ran across "class.gzip_encode.php" whuch is a php class to gzip encode served content to reduce size. It loads your pages faster, reduces server load and makes for a better browsing experience for dial-up users.
This is probably something I will never use, but when I find things like this I like to post them here. I am sure someone will find a use for it.
Get the class file from Leknor.com.
