In the next section we will see how to implement declarative fine grain authorization via the Login View control.Following that, we will explore programmatic techniques.This tutorial starts with a look at how the Roles framework associates a user's roles with his security context.It then examines how to apply role-based URL authorization rules. NET to allow only authenticated users to visit a page.The good news is that the tools at our disposal for applying authorization rules work equally well with roles as they do for user accounts.URL authorization rules can specify roles instead of users.In this case, the cookie will not be sent when making requests to subdomains, such as admin.

A more maintainable approach is to use role-based authorization.Technically, I didn't need to specify values for these attributes since I just assigned them to their default values, but I put them here to make it explicitly clear that I am not using persistent cookies and that the cookie is both encrypted and validated. Henceforth, the Roles framework will cache the users' roles in cookies.If the user's browser does not support cookies, or if their cookies are deleted or lost, somehow, it's no big deal – the Note Microsoft's Patterns & Practices group discourages using persistent role cache cookies.This may entail showing or hiding data based on the user's role, or offering additional functionality to users that belong to a particular role.Such fine grain role-based authorization rules can be implemented either declaratively or programmatically (or through some combination of the two).
