title: How to make the search parameters in http request as dynamic in jmeter
body: <p>http request: <a href="http://ipAddress:Port/SomeResource?Param1=value1&amp;Param2=value2&amp;" rel="nofollow noreferrer">http://ipAddress:Port/SomeResource?Param1=value1&amp;Param2=value2&amp;</a>......</p>
  
  <p>so on.
  This is a http request sample in jmeter that hits a rest api and gets response in JSON format.</p>
  
  <p>Here the challenge is Param1, param2, param3 .... these search parameters number is not constant it may change depending on the call so i am making a csv file that contains rows that contain search parameters in coma separated format.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>CSV file is like
  param1,param2
  param1,param2,param3
  param1</code></pre>
  </div>
  </div>
  </p>
  
  <p>I am using a CSV data configure to pull data from the csv file and put it in the http request</p>
