title: Tomcat JSR356 Websocket - disable permessage-deflate compression
body: <p>I'm, working on a Java servlet which runs on a Tomcat 8.0.18 server and uses the JSR356 websocket API to communicate with a browser.
  By default Tomcat uses the "permessage-deflate" compression to compress the websocket messages in both directions. I want to use no websocket compression, how can it be turned off?
  I have tried to use the compression="off" option in the file server.xml but that didn't change anything.
  How can i turn it off?</p>
