title: jMeter thread sequence
body: <p>I have a JMeter test plan with following http request samplers.</p>
  
  <ol>
  <li>Login</li>
  <li>Call some functionality which needs a logged in user</li>
  <li>Logout</li>
  </ol>
  
  <p>When I execute the test plan with 5 parallel threads, I see that the sampler 2 is called before calling sampler 1 for some threads, which then fails the response assertions.</p>
  
  <p>Is there any way to specify a sequence of samplers to be executed ?</p>
