title: How to manually add WebSocket Header in Jmeter?
body: <p>I am using jmeter plugin (WebSocket Samplers by Peter Doornbosch) for creating websocket requests manually.</p>
  
  <p>Opening the connection to websocket  </p>
  
  <ul>
  <li>I use "Websocket Open Connection" sampler.</li>
  <li>Fill all details (server,port,path)</li>
  </ul>
  
  <p>The connection also requires sessionID.<br>
  I tried http header manager but it doesn't takes up the header while execution. </p>
  
  <p>SO, is there a way to manually add websocket header to the (Websocket open connection) sampler?</p>
