title: Adding custom HTTP headers using JavaScript
body: <p>On an HTML page, while clicking the link of an Image ("img") or anchor ("a") tags, I would like to add custom headers for the GET request. These links are typically for downloading dynamic content. These headers could be SAML headers or custom application specific headers. </p>
  
  <p>Is it possible to add these custom headers through JavaScript? Or if I add these through XMLHttpRequest, how can I achieve the download functionality?</p>
  
  <p>This requirement is for IE6 or 7 only.</p>
