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.
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.
If you have extremely long role names, you may want to consider specifying a smaller , respectively.
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.
Figure 5: Tito Can Visit the Note When specifying URL authorization rules – for roles or users – it is important to keep in mind that the rules are analyzed one at a time, from the top down.
As soon as a match is found, the user is granted or denied access, depending on if the match was found in an URL authorization makes it easy to specify coarse authorization rules that state what identities are permitted and which ones are denied from viewing a particular page (or all pages in a folder and its subfolders).
It can be enabled through the Note The configuration settings listed in Table 1 specify the properties of the resulting role cache cookie.
For more information on cookies, how they work, and their various properties, read this Cookies tutorial. The path attribute enables a developer to limit the scope of a cookie to a particular directory hierarchy.
For more information on this security recommendation, as well as other security concerns, refer to the Security Question List for ASP. parameter, as this parameter indicates that the user arrived at the login page after attempting to view a page he was not authorized to view.A more maintainable approach is to use role-based authorization.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.And the Roles API includes methods for determining the logged in user's roles.This tutorial starts with a look at how the Roles framework associates a user's roles with his security context. NET pipeline it is associated with a security context, which includes information identifying the requestor.
