Asp.net mvc route based on subdomain

Anonymous User 5025 07 Oct 2014

Is it possible to have an ASP.NET MVC route that uses subdomain information to determine its route? For example.

· user1.domain.com goes to one place

· user2.domain.com goes to another?

Or, can I make it so both of these go to the same controller/action with a username parameter?

You can do it by creating a new route and adding it to the routes collection in RegisterRoutes in your global.asax. Below is a very simple example of a custom Route.

public class ExampleRoute : RouteBase
        {
 
            public override RouteData GetRouteData(HttpContextBase httpContext)
            {
                var url = httpContext.Request.Headers["HOST"];
                var index = url.IndexOf(".");
 
                if (index < 0)
                    return null;
 
                var subDomain = url.Substring(0, index);
 
                if (subDomain == "user1")
                {
                    var routeData = new RouteData(this, new MvcRouteHandler());
                    routeData.Values.Add("controller", "User1");                    routeData.Values.Add("action", "Index");
 
                    return routeData;
                }
 
                if (subDomain == "user2")
                {
                    var routeData = new RouteData(this, new MvcRouteHandler());
                    routeData.Values.Add("controller", "User2");
                    routeData.Values.Add("action", "Index");
 
                    return routeData;
                }
 
                return null;
            }
 
            public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
            {
                return null;
            }
        }
