title: Jmeter- How to make a request wait until I get a specific response
body: <p>Request is as :</p>
  
  <ol>
  <li>request_a is sent and i get a response as "in progress"</li>
  <li>Again, request_a is sent and i get a response as "in progress"</li>
  <li>Again, request_a is sent and i get a response of "complete data"</li>
  </ol>
  
  <p>What happening in my target server when its responds "in progress" is that the server is taking time to cache the data in the server. Here, the 3rd request is returned with complete data.</p>
  
  <p>What I need is : all 3 requests should wait until it gets complete data. So that I can check the real load of the request_a connecting to database-fetching data and giving response</p>
  
  <p>Note: I am checking by clearing the cache manually from the server.</p>
