基于站点/ URL的ASP.NET MVC角色授权

Question

I'm creating a single web application that I will be deploying to different sites (eg, red.domain.com, blue.domain.com, etc). I want different roles to have access to the different sites (eg, the "red" role will have access to red.domain.com).

Currently I am using controller-wide authentication (eg, [Authorize(Roles = "red")]). When I deploy my application to a site, I have to change the role on each controller (eg from "red" to "blue"), which seems ridiculous.

Anyone have any ideas on how I can streamline this? Maybe a setting I can create on the IIS site itself that automatically applies the correct role?

Thanks much.

Could be good place for dependency injection. A library like StructureMap allows you to define type mappings in web.config (I'm assuming you have one web.config for each site)

So, if you have RedController and BlueController , that both implement a common interface IColourfulController it would look something like this:

<!-- red web.config-->
 <DefaultInstance
      PluginType="IColourfulController, [assembly name]"
      PluggedType="RedController,  [assembly name]" />

<!-- blue web.config-->
 <DefaultInstance
      PluginType="IColourfulController, [assembly name]"
      PluggedType="BlueController,  [assembly name]" />

// when you need the controller
IColourfulController controller = 
    ObjectFactory.GetInstance<IColourfulController>();

Both sites can use the same code for getting the controller, but the web.config says whether it will be blue or red.
