Handling Duplicate URLs in ASP.NET MVC: www vs non-www

Concerned about duplicate URLs in ASP.NET MVC?

Take care of both www and non-www domains. .NET already provides the correct method to handle them.

Using the UseRewriter middleware is the optimal approach.

You can use AddRedirectToNonWww() or AddRedirectToWww() for this purpose.
