title: Using Apache Benchmark to load the urls from a text file
body: <p>Need to test the performance of API's with variable parameters (x and y) </p>
  
  <p>e.g. <code>http://myapiurl?x=1&amp;y=2&amp;z=6</code>
       <code>http://myapiurl?x=3&amp;y=3&amp;z=6</code>
       <code>http://myapiurl?x=5&amp;y=2&amp;z=6</code>
       ..........</p>
  
  <p>now while bench marking I want to hit the urls randomly from a text file.    </p>
  
  <p><code>$ ab -c 100 -c 500 urls.txt</code></p>
