.NET - Get protocol, host, and port

Question

Is there a simple way in .NET to quickly get the current protocol, host, and port? For example, if I\'m on the following URL:

http://www.mywebsite.com:80/pages

Answer 1

Even shorter way, may require newer ASP.Net:

string authority = Request.Url.GetComponents(UriComponents.SchemeAndServer,UriFormat.Unescaped)

The UriComponents enum lets you specify which component(s) of the URI you want to include.
