title: How to terminate session in Selenium Grid(Extras)
body: <p>How to terminate session in Selenium Grid? My problem is that if my test fail hub still keep session for this test and I can't run another test (it run but fail because can't get free node, because it is registered in hub). I have found this <a href="https://stackoverflow.com/questions/22686920/how-to-kill-thread-in-a-selenium-grid-node">How to kill thread in a Selenium Grid node</a> and there is an answer to use <code>DELETE /session/:sessionId</code> but it didn't work for me. Documentation on Selenium Grid or Extras is very pure, maybe some one have similar issue and know how to resole it?</p>
