Newbie Question: htaccess -- using ErrorDocument

[brand404]

In my .htaccess file i have the following line that will redirect blocked ips to the "blk.php" file:

ErrorDocument 403 /blk.php

However, in the blk.php file i would like to be able to know which page was attempted to be accessed so i can return back the proper error message to the user.

Examples:

1) If the blocked user was trying to access this page: http:// my.website.com/page1.htm then i want "blk.php" to know that the blocked user was trying to access "page1.htm".

2) If the user tries to access: "http:// my.website.com/" then "blk.php" should know it was "/" the user was trying to access.

So the problem is how do i let the blk.php script know what the ORIGINAL Get request page was when the user was attempting to access my site?

Thanks

What server variables have you tried to "read" from within the php code to get this information? I believe the Request_URI variable should still contain the originally-requested URL, but I am not sure that that's the 'exactly-correct spelling' for that variable-name in PHP.
