Custom Identity Authentication

Custom authentication requires the implementation of both IIdentity and IPrincipal interfaces, and this process is done in the authenticaterequest phase. The following procedure is a simulation of the implementation of identity authentication, in this way can be stored in the ticket data to initialize the implementation of the IPrincipal, thereby changing the HttpContext.Current.User point to the object instance.

  <authentication mode="Forms">            <forms loginurl="a.html " name="Andy"></forms>        </authentication>
