ASP.NET 5中的子域路由

Question

I am trying to get sub-domain routing working in my ASP.NET 5 application.

I basically want to map http://api.example.com to a particular controller within my application, http://map.example.com to a different controller etc.

I have looked at various articles about this but they are all out of date and do not work with the latest version of the ASP.NET framework.

The official documentation is missing information on routing. Maybe it's my own fault for trying to use a beta product!

Looking forward to hearing some ideas of how to get this working.

If I understand your intent correctly, ASP.NET routing is not the proper way for this.

If this was for ASP.NET versions before 5.0, I'd have suggested that you intercept the request before it's routed within Application_BeginRequest() and check for HTTP_HOST Request Header value to determine which site the user wanted to visit.

I see that the application flow has changed in a major way with vNext. However, I came across this sample from the ASP.NET MVC 6 source on github that creates a custom route based on a "User" header in the request: https://github.com/aspnet/Mvc/tree/dev/samples/CustomRouteSample.Web I believe this may be the starting template for a similar solution to your issue if you use "HTTP_HOST" header instead.

Good luck, let us know if you're able to implement a working solution.
