Description:
------------
Under IIS, PHP (isapi module) does not set the $_SERVER['PATH_INFO'] variable. 

Also, all requests to a path similar to:
index.php/my/path/info
Throws errors similar to:
Warning: Unknown(C:\Development\index.php\my\path\info): failed to open stream: No such file or directory in Unknown on line 0

Warning: (null)(): Failed opening 'C:\Development\index.php\my\path\info' for inclusion (include_path='.;c:\php4\pear') in Unknown on line 0

This functionality works with Apache and PHP on windows. There are patches to enable this functionality, though it has not been maintained since version 4.2.3.

Reproduce code:
---------------
<?php

// Request url similar to
// index.php/my/path/info

exit($_SERVER['PATH_INFO'];

?>

Expected result:
----------------
/my/path/info

Actual result:
--------------
Warning: Unknown(C:\Development\index.php\my\path\info): failed to open stream: No such file or directory in Unknown on line 0

Warning: (null)(): Failed opening 'C:\Development\index.php\my\path\info' for inclusion (include_path='.;c:\php4\pear') in Unknown on line 0
