I wondered if this would be possible. I’d like to centralize my cakePHP core files at 1 location, and want my several applications to use the same core. One reason is when updating I just need to update one core. Nowadays I always upload the whole cakephp package with each application.
But my applications are not all on the same server.
Unfortunately I’m not sure webservers can access files across physical servers; and even if it could via network shares, this would be an incredible performance hit.
Rather try to automate the core deploy using SVN or RSync tools.
SO, while it may technically be possible, I wouldn’t advise it.
