title: Adding text to a variable on the Authorization header visual studio 2013 load test
body: <p>I am creating some load tests in visual studio 2013.</p>
  
  <p>The test has 2 steps</p>
  
  <ol>
  <li>authentication:  This method returns a token that I need to call the second method, I am getting the value using an extraction rule and I am putting it on a variable called token</li>
  <li>list:  This method returns a list of items that belongs to the user authenticated and I need to send in the header on the authorization value: Bearer token</li>
  </ol>
  
  <p>I have the token but I need to add before that the text: Bearer</p>
  
  <p>I have not been able to concatenate anything through the interface.  I tried generating the test code and adding it there but when it runs it doesn't pick up the code, but the configuration done on the interface</p>
