Applying authorization rules on a user-by-user basis can grow into a bookkeeping nightmare.A more maintainable approach is to use role-based authorization.In particular, we created a page that listed the contents of the current directory.Anyone could visit this page, but only authenticated users could view the files' contents and only Tito could delete the files.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 may entail showing or hiding data based on the user's role, or offering additional functionality to users that belong to a particular role.

The default value is "/", which informs the browser to send the authentication ticket cookie to any request made to the domain. The default value is an empty string, which causes the browser to use the domain from which it was issued (such as

Since possession of the role cache cookie is sufficient to prove role membership, if a hacker can somehow gain access to a valid user's cookie he can impersonate that user.

The likelihood of this happening increases if the cookie is persisted on the user's browser.

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.
