Just turn on gzip compression on your server and everything your server sends to the browser should be already gzip-compressed automatically, which is most likely much, much more efficient. You can see that if your server sends back a "Content-Encoding: gzip" into the http response to your browser. On Chrome, with the debugging tools turned on on the Network tab, you can see "Size/Content" for every request. Size is the actual number of bytes transferred while Content is the size of your uncompressed content.
