title: XMLHTTPRequest and HTTP "Content-Location" header
body: <p>I run XMLHTTPRequest Asynchronously (true) to download some big images and based on the Content-Location information, which is the image filename, my script knows which &lt; IMG > tag it should put the image.</p>
  
  <p>This works if I don't specify the filename extension in the url. If I put full filename + the extension of the image in the url GET, the web server would not reply the Content-Location.</p>
  
  <p>How to force the web server to always return me the Content-Location?</p>
  
  <p>Thanks
