After all, FastCGI forks off a process that handles requests on it's own. So certainly it's possible for mod_php to be upgraded and changed to fork off a PHP application process, which is a first step towards a true PHP application server. That process is long-lived... Once that's done, then the framework is there for each PHP process/AS to load balance and share state. -- Jim Jagielski <jim@zend.com> CTO and PHP Evangelist, Zend Technologies V: 410-420-0140 | F: 410-803-2258 | M: 443-324-8390 http://www.zend.com/
