This explains how to enable a gzipped qooxdoo.js without having this possibility directly built in to your webserver.

If you have php at the server, you can write in your html file:

<script type="text/javascript" src="<<path>>/qooxdoo.php"></script>

Then you create a file called qooxdoo.php with this content:

<?php
   /**
   * @author     Oliver Vogel <o.vogel@muv.com>
   * @since      05.03.2006
   */
   $encodings = array();
   if (isset($_SERVER['HTTP_ACCEPT_ENCODING']))
   {
       // Get all available encodings
       $encodings = explode(',', strtolower(preg_replace("/\s+/", "", $_SERVER['HTTP_ACCEPT_ENCODING'])));
         // Check for gzip header
       if (in_array('gzip', $encodings))
       {
           // found: send the zip-ed file
           header("Content-Encoding: gzip");
           echo file_get_contents(getenv('DOCUMENT_ROOT') . '<<path>>/qooxdoo.js.gz');
           die;
       }
   }
 
   // Encoding not found or gzip not accepted -> send "normal" file
   echo file_get_contents(getenv('DOCUMENT_ROOT') . '<<path>>/qooxdoo.js');
   die;
?>

This page checks if the browser supports gzip. If this is true, the server sends the gzip file to the client. This solution needs no gzip-support at the server-side!

Also, if you are writing your own webserver it is trivial to include this feature directly.

I know, it is NOT JavaScript but maybe it is a good idea to add this to the qooxdoo distribution (and it may be a good idea if one with Python or Perl or other experience ports this script to another server-side programming language).
