[opencms-dev] How is handle404 related to static export?

[Nigel Kersten]

I've got Apache2 and Tomcat working together for multiple sites as  
per the documentation, (my virtual host config is at the end of this  
mail), and there's something I just don't get.

Why do I need the Rewrite stuff for handle404? and how is this  
related to static exports?

thanks for any illumination anyone can shed on this...
