             Summary: support websocket endpoint rewrite
                 Key: KNOX-894
                 URL: https://issues.apache.org/jira/browse/KNOX-894
             Project: Apache Knox
          Issue Type: Improvement
          Components: Server, Site
    Affects Versions: 0.11.0
            Reporter: Zhou Li


As knox websocket consumer, we have one webapp provide the SQL execution service. We use websocket to provider better experience which will notify customer whenever there is notification.
  We have the websocket backend ws://localhost:11080/message-service/messages. we add some extra path and query to provider different service. For example:
ws://localhost:11080/message-service/messages/subscribe?name=XXXX 
provide message channel subscribe service

ws://localhost:11080/message-service/messages/topic?name=XXXX
provide message channel for specific features

ws://localhost:11080/message-service/messages/unsubscribe?name=XXXX
provide message channel for unsubscribe service

I want to define the rewrite.xml as something like 
<rules>
  <rule dir="IN" name="WSSERVICE/ws/inbound" pattern="*://*:*/**/message-service/messages/**?{**}">
    <rewrite template="{$serviceUrl[WSSERVICE]}/**?{**}"/>
  </rule>
</rules>

and configure service like 
<service>
        <role>WSSERVICE</role>
        <url>ws://localhost:8000/message-service/messages</url>
</service>
