title: how to GET and search response contain the file then proceed to next HTTP request
body: <p>I have a scenario that</p>
  <pre><code>1. user upload a file - system process take 10mins -
  2. then the user can transfer the file 
  </code></pre>
  <p>I cannot do load test in a Thread - #1 then #2 because of the processing time (#2 is performing too quickly before the file is ready for transfer).</p>
  <p>I am thinking to keep sending GET requests and finding the response containing the file name then proceeding to #2.</p>
  <p>I can only use GET API to get a list of files (API does not support specific file search, the GET return list of file in response)</p>
  <p>is that a good approach? how can I do it?</p>
