Using GZIP compression

GZIP compression greatly reduces the bandwidth needed for loading HTML pages and text resources like JavaScript files and CSS stylesheets. [fleXive] does not come with its own GZIP filter, since this service is often provided by the application server.

Enabling GZIP compression on Glassfish 2

• Open the Glassfish administration console (http://localhost:4848/)
• Open Configuration > HTTP Service > HTTP Listeners
• Select the listener for the desired port (e.g. http-listener-1)
• Add the following properties on the bottom of the page:
  • compression=on
  • compressableMimeType=text/html,text/xml,text/plain,text/css,text/javascript,application/json
• Now all the responses should be encoded using GZIP. You can check this using a tool like Firebug for Firefox or any other HTTP header viewer.
