MobileFormsAuthentication.RedirectFromLoginPage Method (String, Boolean, String)

 

Redirects an authenticated user to the originally requested URL after logging in. This API is obsolete. For information about how to develop ASP.NET mobile applications, see the www.asp.net/mobile Web site.

Namespace:   System.Web.Mobile
Assembly:  System.Web.Mobile (in System.Web.Mobile.dll)

Public Shared Sub RedirectFromLoginPage (
	userName As String,
	createPersistentCookie As Boolean,
	strCookiePath As String
)

Parameters

userName
Type: System.String

Name of the user for cookie authentication purposes. This does not need to map to an account name and is used by URL Authorization.

createPersistentCookie
Type: System.Boolean

Specifies whether or not a durable cookie (one that is session based or outlasts the session) must be issued.

strCookiePath
Type: System.String

Returns the configured cookie path used for the current application.

The methods create an encrypted string from the authentication cookie and append it to the redirecting URL of the originating request. A client-side redirect is then issued for that URL. This can be used to work around the limitations of certain mobile devices that either do not support cookies, or support cookies that are too small for storing authentication information in a secure manner.

The following example demonstrates how to use the RedirectFromLoginPage method to send the authenticated user back to the URL that was originally requested.
