             Summary: Support WebSockets ping/pong keep-alive in Gremlin server
                 Key: TINKERPOP-1726
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1726
             Project: TinkerPop
          Issue Type: Improvement
          Components: server
    Affects Versions: 3.2.5
            Reporter: Andy Davidoff


The ping/pong keep-alive system that is part of the WebSockets spec provides for successful identification of a dropped connection from either end of the connection.

Currently, the Java client successfully issues keep-alive pings and receives pong replies from the server.  Unfortunately, the server does not actively ping clients, nor does it discover and react to dead clients when keep-alive fails.

This can cause pending client writes to lock up the server indefinitely when a client spontaneously disconnects.
