FormsAuthentication.RedirectToLoginPage Method
Redirects the browser to the login URL.
Assembly: System.Web (in System.Web.dll)
The RedirectToLoginPage method redirects the browser to the LoginUrl.
The RedirectToLoginPage method does not clear the forms-authentication cookie. You can use the RedirectToLoginPage method in conjunction with the SignOut method to log one user out and allow a different user to log in.
The following code example clears the forms-authentication cookie using the SignOut method and redirects the user to the login page using the RedirectToLoginPage method.
