ASP NET MVC Include Url Parameter on all pages

Question

I have an ASP NET MVC application that is multi-client and multi-user, IE, it is prepared to be used by multiple customers and each client can have multiple users.

Initially the login form has the text input for the client code. However I want to perform some routing for the user to inform the client code directly in the URL, I know that using the standard routing I can get this code taking the value of the parameter id in the controller, but this only works on the first page if some redirect is performed I can’t get this information.

How should I implement this? below my Routeconfig class:

    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute("Default", "{controller}/{action}/{id}",
                new {controller = "Acesso", action = "Login", id = UrlParameter.Optional});
        }
    }

Suppose you want a url in this pattern:

/empresaId/clientes/clienteId 

That could be translated to:

/1/clientes/10

You can create a route:

    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute("Empresa", "{empresa}/{controller}/{action}/{id}",
                new { action = "Index", id = UrlParameter.Optional});

            routes.MapRoute("Default", "{controller}/{action}/{id}",
                new {controller = "Acesso", action = "Login", id = UrlParameter.Optional});
        }
    }

Set the company parameter in the controller:

public class Clientes : Controller 
{
    // rota: /1/clientes/10
    public ActionResult Index(int empresa, int id) 
    { 
    }

    // rota: /1/clientes/editar/10
    public ActionResult Editar(int empresa, int id) 
    { 
    }
}

Create a Session for the company id on login:

var empresaId = 1;
Session.Add("empresa", empresaId);

To then create the links, you make use of Session by passing the company parameter:

@Html.Action("index", "clientes", new { empresa = Session["empresa"] })

or

@Html.ActionLink("editar", "clientes", new { empresa = Session["empresa"] })

or

@Url.Action("index", "clientes", new { empresa = Session["empresa"] })

I think something like this could solve your problem:

routes.MapRoute("Default", "Cliente/{id}",
            new {controller = "Cliente", action = "Pesquisar", id = UrlParameter.Optional});

Your controller would look like this:

public class Cliente : Controller 
{
    public ActionResult Pesquisar(int id) // id seria o código do cliente
    { ... }
}

The call would look like this:

localhost/Client/12345
