Run Php4 For .php4 Files And Php5 For .php [httpd.conf]

First off my error: apache force downloads .php4 files

Background:
Im attempting to run php4 and php5 at the same time. I had php 5 installed with the server when I got it.

I have installed php 4 from the source like this:

Code:
./configure --with-apxs=/usr/local/apache/bin/apxs --prefix=/PHP4 --without-mysql
I then copied the php.ini file to /PHP4/php.ini

In my httpd.conf Im loading and adding both php 4/5 modules like so:

Code:
LoadModule php4_module libexec/libphp4.so
LoadModule php5_module libexec/libphp5.so

AddModule mod_php4.c
AddModule mod_php5.c
Then later in the httpd.conf Im trying to tell apache to handle .php4 files with PHP 4 and .php with PHP5

Code:
AddType application/x-httpd-php .php
AddType application/x-httpd-php4 .php4
I restarted apache to load the new conf. .php files still use PHP5, but for some reason .php4 files are being downloaded, not running with PHP 4.

If I use htaccess to application/x-httpd-php4 php, .php files also force download. What am I missing?
