FastCGI and PHP

Hi,

I don't understand exactly how FastCGI/Apache2/PHP works together.

Actually i have this :

Real directory :

/var/www/fcgi/

Inside this :

rphp => the php executable

php => the following script :

#!/bin/sh
PHPRC="/etc/php/php.ini"
export PHPRC
PHP_FCGI_CHILDREN=1
export PHP_FCGI_CHILDREN
exec /var/www/fcgi/rphp


Now in the Apache conf :

ScriptAlias /fcgi/ "/var/www/fcgi/"
FastCgiWrapper On
FastCgiExternalServer /var/www/fcgi/php -host 127.0.0.1:8008
AddHandler php-fastcgi .php
<Location /fcgi/php>
        SetHandler fastcgi-script
</Location>
Action php-fastcgi /fcgi/php
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps


This works, but what is the fonction of FastCgiExternalServer ?
I ask this because i don't have a process like /var/www/fcgi/rphp -b
127.0.0.1:8008 running and that works nevertheless.


Thanks for your help

Regards,

Raphaël
