Does Request.Url.Host include the subdomain?

Question

e.g. for mail.google.com would it return google.com or mail.google.com? I can't actually test it myself

Because I'm changing an already live system. I can't deploy this. Running locally gives me localhost for Request.Url.Host — Adam Lynch, Jul 06 '11 at 09:52

You can save yourself from the headache of waiting for answers by reading documentation on Msdn.

A String that contains the host name. This is usually the DNS host name or IP address of the server.

If the requested DNS record is a subdomain, that's the record it will return. Subdomains are still there own records in a zone file, so its not going to return just the root domain because that's not the same record, nor request.

I was also curious as to why you couldn't test this, but if its because of the lack of an internet connection (maybe you're posting from mobile I don't know) you can add your own records to the Windows HOSTS file and test locally.

Harder to test when you're on localhost – Savage Jun 18 '20 at 10:02 — Savage, Jun 18 '20 at 10:02
