You are designing an ASP.NET MVC 2 Web application for a customer’s extranet site. You
need to allow only requests that originate from the customer’s intranet IP address range to
access the application, and you must redirect other access requests to the customer’s Web
site. Which approach should you recommend?

A.
Design the default controller and action to check the IP address and to redirect requests
from outside the specified IP address range to the public Web site.

B.
Configure the IIS URL Rewrite module to redirect requests from outside the specified IP
address range to the public Web site.

C.
Configure IIS to reject requests from outside the specified IP address range.

D.
Configure the IIS Request Filter module to filter requests.
