Multiple routes and global attributes

hi guys

I am playing around with razor pages and building a new website with it.

1. How do I add a global configuration to all the files in a folder e.g Pages >> Accounts folder (I know in webforms I could add this in the root web.config file or in MVC I could add the attribute to the root controller e.g the [Authorize] attribute and it would apply to all controller actions
2. How do I add multiple routes to a page as I have Pages >> Admin  which I want to be either administrator or admin currently I am using @Pages "/Admin"

thanks

Ehi
