title: Titan Gremlin Server is giving Error "not a WebSocket handshake request: missing upgrade"
body: <p>I downloaded Titan Version 1.0 on EC2 server from url</p>
  
  <p><a href="http://s3.thinkaurelius.com/downloads/titan/titan-1.0.0-hadoop1.zip" rel="nofollow noreferrer">Titan 1.0.0 with Hadoop 1 – recommended</a></p>
  
  <p>Then I unzip and ran the titan server with following command :</p>
  
  <blockquote>
    <p>bin/titan.sh start</p>
  </blockquote>
  
  <pre><code>Forking Cassandra...
  Running `nodetool statusthrift`... OK (returned exit status 0 and printed string "running").
  Forking Elasticsearch...
  Connecting to Elasticsearch (127.0.0.1:9300).... OK (connected to 127.0.0.1:9300).

  </code></pre>
  
  <p>Then I tried from HTTP Request in Titan 1.0 Version (in titan 0.4 version Rexster is working properly)
  But I'm getting following Error</p>
