Skip RedirectFromLoginPage in ASP.Net

Problem:
You have a web application that has a specific redirect page after user logs into the application. But, in certain circumstances, you want to skip it and redirect the user to another page instead of the default page specified after user usually logs into the application.

Solution:
Thanks to a thread from VelocityReviews, I find the solution.
Instead of using

FormsAuthentication.RedirectFromLoginPage(userName, createPersistantCookie) 

use

FormsAuthentication.SetAuthCookie(userName, createPersistantCookie) 

and

Repsonse.Redirect(url)

methods to redirect the user to the page you want.
