title: CORS header 'Access-Control-Allow-Origin' missing but it present in the header
body: <p>I need read to read remote content. I read that should be send header <code>Access-Control-Allow-Origin</code>. I did that but still get this error. Here is script code</p>
  
  <pre><code>        $.ajax({
              url:'http://bbc.co.uk',
              headers: {'Access-Control-Allow-Origin': '*'},
              success:function(json){
                  // do stuff with json (in this case an array)
                  alert("Success");
              },
              error:function(){
                  alert("Error");
              }
          });
  </code></pre>
  
  <p>I see Access-Control-Allow-Origin in the sent headers. What is wrong?</p>
