Description:
------------
I would like to user $_SERVER['PATH_INFO'] in one of my search-engine friendly script but unfortunately, it is not available under Apache 2.2, PHP 5.2 RC5 installed as a module. PHP engine said: Undefined index: PATH_INFO

Reproduce code:
---------------
Sample code

index.php in mod_rewrite folder

<a href="http://localhost/mod_rewrite/forum/21/3.html">url</a>
<?php
var_dump($_SERVER['PATH_INFO']);
?>

.htaccess in mod_rewrite folder

AcceptPathInfo On
RewriteEngine On
Options +FollowSymLinks
RewriteRule ^index.php(/.*) /index.php [E=PATH_INFO:$1,L]
RewriteRule ^(.*)/(.*)/(.*).html http://localhost/mod_rewrite/index.php?module=$1&cid=$2&topic=$3

=============================================
My environment
=========My PHP directives in httpd.conf of Apache 2.2.3

LoadModule php5_module "c:/server/php5/php5apache2_2.dll"
AddType application/x-httpd-php .php
PHPIniDir "c:/server/php5"

<Directory "D:/webroot">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.2/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   Options FileInfo AuthConfig Limit
    #
    AllowOverride All

    #
    # Controls who can get stuff from this server.
    #
    Order allow,deny
    Allow from all

    AcceptPathInfo On

</Directory>

Expected result:
----------------
I expected that when I click on the link http://localhost/mod_rewrite/forum/21/3.html the value of PATH_INFO will be printed out from http://localhost/mod_rewrite/index.php because .htaccess should be routed the request to index.php.

Actual result:
--------------
The script has printed out: 

Notice: Undefined index: PATH_INFO in D:\webroot\mod_rewrite\index.php on line 3
NULL
