title: JMeter: Generate value for custom Header with a java class
body: <p>i try to test the performance for our api which has a request-limiter (100requets in 100sec otherwise the ip is blocked).
  You can avoid this with a custom header. The value for this header is generate by a java class.</p>
  
  <p>With jruby i can use "require" and "import" too use the class.</p>
  
  <p>How can i do this for JMeter?</p>
  
  <p>Additional infos:
  the header value is dynamic -> for each request it has to be generated. 
  To call HttpPwd.genPwd() two *.jar files are needed</p>
