title: Jmeter - HTTP Cookie Manager and HTTP Header Manager conflict
body: <p><strong>Hello everyone.</strong></p>
  <p>I am working with JMeter and I found one conflict between HTTP Cookie Manager and HTTP Header Manager. I am not sure how to process it.</p>
  <p><strong>What should be done:</strong></p>
  <p>I need to add extra data into the &quot;Cookie Data:&quot; section from the &quot;Request Body&quot;.</p>
  <p>I found this solution:</p>
  <ol>
  <li>Add &quot;HTTP Header Manager&quot;.</li>
  <li>Add name: &quot;Cookie&quot; with needed value.

  <li>As you can see from the screenshot - I am adding &quot;Cookie&quot; values in the &quot;HTTP Header Manager&quot;.
  As a result, I get this:

  <li>As you can see from the screenshot - I was able to add data into the &quot;Cookie Data:&quot; request from the &quot;Request Body&quot;.</li>
  </ol>
  <p><strong>What's the problem:</strong></p>
  <ol>
  <li>I use &quot;HTTP Cookie Manager&quot; too.</li>
  <li>When I execute a sample with data that came from the &quot;HTTP Cookie Manager&quot; and data came from the &quot;HTTP Header Manager&quot; - JMeter doesn't add data from the &quot;HTTP Header Manager&quot;.

  <li>As you can see from the screenshot - I add the &quot;Cookie&quot; header into the &quot;HTTP Header Manager&quot;.</li>
  <li>As a result, I am expecting to get this data into the &quot;Cookie Data&quot; area of the request. But... I see only the data came from the &quot;HTTP Cookie Manager&quot;.

  <li>As you can see from the screenshot - added data from the &quot;HTTP Header Manager&quot; is missing in this &quot;Cookie Data&quot; section from the request.</li>
  </ol>
  <p>I researched in google and try a lot of things - but without result.</p>
