I have some questions concerning the Zend Framework. I am attempting to route all static pages through the default controller using the now default displayAction()
I think your on the right track however here are some other ideas.
Break up your routing per sections in your INI: ie a blog router, a static page router a forum router etc.. (I think you are already doing this)
Use the various router classes to handle routing per section rather than sending it to a controller.
Static: http://framework.zend.com/manual/en/zend.controller.router.html#zend.controller.router.routes.static
All: http://framework.zend.com/manual/en/zend.controller.router.html
