FormsAuthenticationEventArgs.User Property
Gets or sets the IPrincipal object to be associated with the current request.
Assembly: System.Web (in System.Web.dll)
Property Value
Type: System.Security.Principal.IPrincipalThe IPrincipal object to be associated with the current request.
You can use the User property to set the User property of the current HttpContext to a custom IPrincipal object.
If you do not specify a value for the User property during the FormsAuthentication_OnAuthenticate event, the identity supplied by the forms authentication ticket in the cookie or URL is used.
The following example uses the FormsAuthentication_OnAuthenticate event to set the User property of the current HttpContext to a GenericPrincipal object with a custom Identity.
Public Sub FormsAuthentication_OnAuthenticate(sender As Object, _ args As FormsAuthenticationEventArgs) If FormsAuthentication.CookiesSupported Then If Not Request.Cookies(FormsAuthentication.FormsCookieName) Is Nothing Then Try Dim ticket As FormsAuthenticationTicket = FormsAuthentication.Decrypt( _ Request.Cookies(FormsAuthentication.FormsCookieName).Value) args.User = New System.Security.Principal.GenericPrincipal( _ New Samples.AspNet.Security.MyFormsIdentity(ticket), _ New String(0) {}) Catch e As HttpException ' Decrypt method failed. End Try End If Else Throw New Exception("Cookieless Forms Authentication is not " & _ "supported for this application.") End If End Sub
