When you are using the ASP.NET Development Server to test your ASP.NET Web pages, you might receive a 502 error or an error indicating that the page cannot be displayed. If so, your browser might be unable to resolve a URL containing localhost and a port number, such as the following:
http://
localhost:8080
/MyWebSite/Default.aspx
