title: Writing a simple JMeter script
body: <p>I need to write a script that does the following (doesn't matter to which website, I am only doing this to learn and practice): </p>
  
  <ol>
  <li>Simulates HTTP requests (method: get)</li>
  <li>Reads parameters from a document and uses them in the script</li>
  <li>Saves an expression from the response of the request and uses it as a
  parameter in the next request    </li>
  <li>Saves the output to a file</li>
  </ol>
  
  <p>After a few hours of reading the documentation and watching some video tutorials, I can manage step 1 easily. I have a little idea on how to do steps 2 and 4 though there might be a chance that I am not doing them efficiently. And unfortunately I have no idea how to do step 3. </p>
  
  <p>Can someone help me in doing those steps please or at least give me some good links to tutorials that may help me out (I've found the official manual too confusing)?</p>
  
  <p>Here are some links I used to learn this tool: <a href="http://www.youtube.com/watch?v=ovzybIDwn_k" rel="noreferrer">For step 1</a> and <a href="http://ivetetecedor.com/192/how-to-use-a-csv-file-with-jmeter" rel="noreferrer">for step 2</a> they helped a little but more guidance is welcomed. </p>
