title: How to parse Jmeter response and make a new request
body: <p>I'm using jMeter to test a Tomcat application. I need to parse the jMeter response and make a second request. The first response looks like this:</p>
  
  <pre><code>&lt;responseData class="java.lang.String"&gt;&amp;lt;html&amp;gt;&amp;#xd;
  &amp;lt;body&amp;gt;&amp;#xd;
  ERROR=0&amp;#xd;
  MSG=N/A&amp;#xd;
  FILELIST=1555;1340778737370;1526545487;&amp;#xd;
  VERSION=1.002&amp;#xd;
  URL=https://192.168.100.46/updserver/download?action=signature_download&amp;amp;token=&amp;#xd;
  INTERVAL=0&amp;#xd;
  &amp;lt;/body&amp;gt;&amp;#xd;
  &amp;lt;/html&amp;gt;&amp;#xd;
  &lt;/responseData&gt;
  </code></pre>
  
  <p>I need to extract the "FILELIST" and "URL" variables and inject them into a new URL:</p>
  
  <pre><code>https://192.168.100.46/updserver/download?action=signature_download&amp;amp;token=1555;1340778737370;1526545487;&amp;#xd;
  </code></pre>
  
  <p>I know there is some post-processor to do that, but no clue how to do it. BTW, the second request will download some file from the Tomcat servlet, is there a way to let jMeter just download the stream but without writing to a physical file? So that I could do a load performance test against my servlet.</p>
