title: How to use user defined variable in Jmeter as server name or Ip while writing scripts using Transaction controller and Test script controller
body: <p>When I am using the Jmeter while recording the script, I want to use a user-defined variable which is the website address. When an HTTP request is created by the Test script recorder, the Server name or IP is created automatically, but what I want is to set those server names manually using a variable.
  How can I do that?</p>
