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 JBoss 4.2

• Open [JBoss-Home]/server/default/deploy/jboss-web.deployer/server.xml
• Add the following attributes to the Connector element for your HTTP port (usually 8080):
  compression="on"
  compressableMimeType="text/html,text/xml,text/plain,text/css,text/javascript,application/x-javascript"
• Your connector element should look similar to this now:

  <Connector port="8080" address="${jboss.bind.address}"    
           maxThreads="250" maxHttpHeaderSize="8192"
           emptySessionPath="true" protocol="HTTP/1.1"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true"
           compression="on" 
           compressableMimeType="text/html,text/xml,text/plain,text/css,text/javascript,application/x-javascript"/>

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.
