I don't know, the url being shown is "request.php?=123" with the ? 
preceding the =123.

? starts the query string in a GET request which is usually one or more 
name=value pairs separated by ampersands, and which can be accessed with 
php using the $_GET[] array. Additionally the whole query string is 
accessible as $_SERVER['QUERY_STRING'], in which case php code can parse 
it as a string, rather than by using the $_GET[] array.

"request.php?=123" will generate an empty $_GET[] array, but will place 
the string "=123" in $_SERVER['QUERY_STRING'].

The following php can be used to demonstrate this (if it formats 
correctly, or maybe even if if it doesn't).

<?php

$get = print_r($_GET, true);

echo <<< EOT

        <td>\$_SERVER['QUERY_STRING']:</td>
        <td>{$_SERVER['QUERY_STRING']}</td>
      </tr>
      <tr>
        <td>\$_GET[]:</td>
        <td><pre>{$get}</pre></td>
      </tr>
    </table>
  </body>
</html>
