title: How to setup authorization Header / Reset existing Header?
body: <p>I am working on the api test with Rest-Assured, and my scenarios are 
  1.Upload 
  2.GetContent</p>
  
  <p>I tried adding </p>
  
  <pre><code>RestAssured.given().auth().basic(userName, password)
  </code></pre>
  
  <p>It doesnt authenticate me and set the header, am getting unauthenticated error.</p>
  
  <p>I also tried adding</p>
  
  <pre><code>RestAssured.given().header("authorization", ConfigHelper.getString(user));
  </code></pre>
  
  <p>Getting the same error. The only thing that worked for me is , </p>
  
  <pre><code>getRequest().header("authorization", ConfigHelper.getString(user));
  </code></pre>
  
  <p>But the problem that I have using getRequest is that am unable to reset the request with scenario 1 and 2, so if I have set authorization in scenario1 and when I try to authenticate in Scenario 2 its duplicating the authentication in Header and giving me a </p>

  <p>error. Is there a way I could reset the header?</p>
