title: Jetty 9 and GzipHandler
body: <p>I'm trying to configure a Jetty 9 server to serve data Gzip compressed. Unfortunatelly I can't find any description that fits to my use case.
  I think I have to use the new GzipHandler instead of the GzipFilter (starting from Jetty 9.3 the GzipFilter is just an dummy).</p>
  
  <p>My setup is a WAR file which is deployed on a Jetty 9 installation or will be run by the maven-jetty-plugin. So this is no embedded Jetty.
  Currently I just have an <code>jetty-env.xml</code> in <code>/src/main/resources/META-INF/resources/WEB-INF</code>. There are no other Jetty related config files.
  I would appreciate a setup which doesn't need any changes on the Jetty installation. So it should be possible to enable the compression just by additional configuration in the WAR file.
  I also like to compress static (files from <code>/src/main/resources/</code> and Webjars) and dynamic (generated by Jersey) content.</p>
  
  <p>I hope that someone already did such an setup and can give me some hint.</p>
  
  <p>Regards,
  Johannes</p>
