I have a simple ASP.NET 3.5 application running under IIS7 under a virtual directory. So the URL of my app is like http://site.com/app. I want to 301-redirect the request to site.com/app/default.aspx to site.com/app for better SEO. Is there any solutions with .Net 4.0.
Check out URL Rewrite. It's the perfect tool for this situation and there are some wizards that will help with the basic SEO redirects.
