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.
