ASP.NET MVC: How to reliably get the real URL of the current request?

Question

Right now I have an MVC application running on http://127.0.0.1:8081/ (it is actually running in the Azure compute emulator). The browser location bar clearly says 8081 for the port number.

However, Request.Url and Request.RawUrl both give me http://127.0.0.1:8082/.

I need to send an e-mail with a URL in it, so I need the correct hostname and port number. How do I get the actual, real URL reliably and without such unexpected deviation?

Answer 1

You can use Request.Headers["Host"]; which will give you the host name (or IP) with the correct port number. Then you can reconstruct the URL.
