How should I get a specific part of the URI
===

If I have the URI "http://www.test.com/something" and I want the "www.test.com" part. 
What should I use? (what is the best for this) 

 - Request.Url.DnsSafeHost
 - Request.Url.Host
 - Request.Url.Authority

I made this question in the [CHAT][1], but didn't get so much luck.
