title: $http response header message
body: <p>is it possible in anulgarjs to fetch the response header message?</p>
  
  <p>in a code similar to that</p>
  
  <pre><code>$http.get(url)
      .success(){
           something
      }.error(status,"headers text message)"{
               alert(status+" "+"headers text message or a method to get it";
      }
  </code></pre>
  
  <p>in the alert i need to write somthing like that:
  500 internal server error.
  In the console log i can see the error status and text message,
  what do i have to put in the error case? what is the best way to do that?</p>
