Asp.net-mvc – What’s the best method in ASP.NET to obtain the current domain

asp.netasp.net-mvcdomain-name

I am wondering what the best way to obtain the current domain is in ASP.NET?

For instance:

http://www.domainname.com/subdir/ should yield http://www.domainname.com
http://www.sub.domainname.com/subdir/ should yield http://sub.domainname.com

As a guide, I should be able to add a url like "/Folder/Content/filename.html" (say as generated by Url.RouteUrl() in ASP.NET MVC) straight onto the URL and it should work.

Same answer as MattMitchell's but with some modification. This checks for the default port instead.

Edit: Updated syntax and using Request.Url.Authority as suggested

$"{Request.Url.Scheme}{System.Uri.SchemeDelimiter}{Request.Url.Authority}"

Assuming you have a Request object available, you can use:

string.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Authority, Url.Content("~"));

If it's not available, you can get to it via the context:

var request = HttpContext.Current.Request

Asp.net-mvc – What’s so RESTful about ASP.NET MVC

There's nothing preventing you from having routes like resource/id with HTTP methods GET/PUT/POST/DELETE in ASP.NET MVC. It's not the default routes setup but you can do it.

EDIT (MLaritz - Adding Darin's comment): ASP.NET MVC is a server side technology allowing you to expose RESTful urls. The way they are consumed doesn't matter. You asked about why ASP.NET MVC is considered RESTFul technology and the answer is because you can easily expose RESTFul urls for consumption, it's as simple as that.
