MobileFormsAuthentication.RedirectFromLoginPage Method (String, Boolean)

Redirects an authenticated user to the originally requested URL after logging in.

Namespace: System.Web.Mobile
Assembly: System.Web.Mobile (in system.web.mobile.dll)

public static void RedirectFromLoginPage (
	string userName,
	bool createPersistentCookie
)
public static void RedirectFromLoginPage (
	String userName, 
	boolean createPersistentCookie
)
public static function RedirectFromLoginPage (
	userName : String, 
	createPersistentCookie : boolean
)
Not applicable.

Parameters

userName

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

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

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 uses the RedirectFromLoginPage method to send an authenticated user to the originally requested URL.
