title: JMeter - cookies no clearing on each new test run
body: <p>I'm building a test in Jmeter and have hit a seemingly trivial problem, but I cannot find a way to overcome it.</p>
  
  <p>I need to start a new session each time the test runs (I'm building in the GUI). I thought that setting the HTTP cookie manager in the Thread Group with the 'Clear cookies on each iteration' setting checked would clear the cookies on each new run of the test.</p>
  
  <p>It doesn't seem to work however - when running a test for the second time the user session initiated in the previous run is still there.</p>
  
  <p>In fact I am now getting a 494 server error (Cookie too large) because the cookies are accruing in size with each run of the test.</p>
  
  <p>Any ideas on how to clear the cookies with each new run of the test?</p>
