MVC dynamic URL

Question

As I know the urls in MVC model is based on the controllers. But I'm facing this problem that I can't wrap my head around it :

What if I'm designing a beverage website, and I have to use different URL for each brand. For example : beverage.com/pepsi, beverage.com/cocacola, beverage.com/sprit, beverage.com/7up. These URLs will all lead to a same page called productdescription, the only difference is the description (image, ingredients, price etc)
So is there any efficent way for this task? I don't want to create new controlers for each product!

Assuming that your common controller name is ProductController and Method name is Description. Now in RouteConfig.cs you can add route as mentioned below:

routes.MapRoute(
    "PepsiRoute",
    "Pepsi/{id}",
    new { controller = "Product", action = "Description", id = UrlParameter.Optional });

routes.MapRoute(
    "CockRoute",
    "Cock/{id}",
    new { controller = "Product", action = "Description", id = UrlParameter.Optional });

Note: Above routes should be placed before default route. Otherwise you will face run-time exception The controller for path '{PATH}' could not be found.

Update:

For multiple brands if you don't want to register route for specific brand then you can map route as mentioned below:

routes.MapRoute(
    "AllBrand",
    "Product/{name}/{id}",
    new { controller = "Home", action = "About", id = UrlParameter.Optional });

Then your URL will be :

{domain}/Product/Pepsi
{domain}/Product/Pepsi/2
{domain}/Product/Cock/14
{domain}/Product/Cock

etc...

Thanks for the answer! Just to clarify: so if there are more brands, I will have to add more map routes?

I can't test right now, but it seems like it's the solution I'm looking for. Thanks for the answer !

You are looking for a Rest Controller. Here are the steps:

1-Declare your rest servlet en web.xml (Websphere example):

<servlet>
    <servlet-name>MyRestServlet</servlet-name>
    <servlet-class>com.ibm.websphere.jaxrs.server.IBMRestServlet</servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>mipackage.MyRestServlet</param-value>
    </init-param>
    <init-param>
        <param-name>requestProcessorAttribute</param-name>
        <param-value>2</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>MyRestServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

2-Implement the RestServlet

import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.core.Application;

public class RestServlet extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> classes = new HashSet<Class<?>>();
        classes.add(BeverageController.class);
        return classes;
    }

}

3-Implement your Rest Controller:

import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;

@Path("/{beverage}")
@ApplicationScoped
public class BeverageController {
    {
        @GET
        public String getBeverage(@PathParam("beverage") String beverage){
            //fetch order
        }
    }  
}
