This series will cover both authentication and authorization. The first article in the series gives a general overview of authentication and authorization in ASP. Other topics describe common authentication scenarios for Web API. Web API assumes that authentication happens in the host. When the host authenticates the user, it creates a principal , which is an IPrincipal object that represents the security context under which code is running. The host attaches the principal to the current thread by setting Thread.

The principal contains an associated Identity object that contains information about the user. If the user is authenticated, the Identity. IsAuthenticated property returns true. For anonymous requests, IsAuthenticated returns false.

For more information about principals, see Role-Based Security. Instead of using the host for authentication, you can put authentication logic into an HTTP message handler. In that case, the message handler examines the HTTP request and sets the principal. Generally, if you don't need to support self-hosting, an HTTP module is a better option. If you need to support self-hosting, consider a message handler. If your application performs any custom authentication logic, you must set the principal on two places:.
