Re: Include client IP address in rewritten URL

This might be obvious, but still:
all of the programming languages I know of can access REMOTE_ADDR even if they don't get it via GET vars. For instance, in PHP you can get it from $_SERVER['REMOTE_ADDR']. So there should be no need to use GET vars, just change the way you access the data. The change should be trivial.

If the code is not yours and you are not allowed to change it, there could still be some way to fix this. For instance, in PHP you could try autoprepending this code:
<?php
  $_REQUEST['REMOTE_ADDR'] = $_GET['REMOTE_ADDR'] = $_SERVER['REMOTE_ADDR']; ?>
That's ugly, of course, but it should still be much faster than Apache rewrite.

YMMV. Anze
