How to get the page origin in razor?

Question

I'm looking for the equivalent of this javascript

window.location.origin

but server side, while building mvc pages.

For example, if you are here http://website.com/123, it would return

http://website.com

Its important that i have the "http://" part

Answer 1

I'm a fan of

string url = Request.Url.PathAndQuery.length > 1
  ? Request.Url.AbsoluteUri.Replace(Request.Url.PathAndQuery, string.Empty)
  : url;

Keeps your Http/Https, Port (if applicable), and HostName/IP.

Updated to Account for PathAndQuery length of 1.
