HOW MANY BSP APPLICATIONS?

Hi everybody,

I'm starting to develop stateful web applications and I have I doubt: how many BSP applications I need to create?

I mean, if I want to create a menu with several diferent items, shall I create only one BSP application to stored mime objects, pages with flow logic and page fragments or is better if I create diferent BSP applications?

I'm talking about 100 or more pages (flow logic and fragments), css style sheets, xml documents, icons, images and more.

Which are de advantages and disavantages to use only one BSP application or several more.

Thanks so much in advanced.

Best regards,

Susana
