copied!<p>What you can do is use the per-route message handler but be careful here. As the article that @Nick linked in his answer, you can chain the handler and ensure that the <code>HttpControllerDispatcher</code> is involved. Otherwise, you won't get into the Controller pipeline.</p> <p>One other option which I like is to use the <code>HttpControllerDispatcher</code> as a base class for your custom handler:</p> <pre><code>public class CustomerOrdersDispatcher : HttpControllerDispatcher { public CustomerOrdersDispatcher(HttpConfiguration config) : base(config) { } protected override Task<HttpResponseMessage> SendAsync( HttpRequestMessage request, CancellationToken cancellationToken) { // Do some stuff here... return base.SendAsync(request, cancellationToken); } } </code></pre> <p>Here, how you will register it:</p> <pre><code>protected void Application_Start(object sender, EventArgs e) { var config = GlobalConfiguration.Configuration; config.Routes.MapHttpRoute( name: "CustomerOrdersHttpRoute", routeTemplate: "api/customers/{customerKey}/orders/{key}", defaults: new { controller = "CustomerOrders", key = RouteParameter.Optional }, constraints: null, handler: new CustomerOrdersDispatcher(config) ); config.MessageHandlers.Add(new SomeOtherHandler1()); config.MessageHandlers.Add(new SomeOtherHandler2()); } </code></pre> <p>After <code>SomeOtherHandler1</code> and <code>SomeOtherHandler2</code> are executed, your <code>CustomerOrdersDispatcher</code> will be executed for <strong>CustomerOrdersHttpRoute</strong> route. So, you can see that you preserve the default handler behavior and set some global handlers while you have a route specific one as well.</p> <p>Here is the full implementation of my <code>CustomerOrdersDispatcher</code>: <a href="https://github.com/tugberkugurlu/AdvancedWebAPI/blob/master/PerRouteMHOwnershipSample/Dispatcher/CustomerOrdersDispatcher.cs" rel="noreferrer">https://github.com/tugberkugurlu/AdvancedWebAPI/blob/master/PerRouteMHOwnershipSample/Dispatcher/CustomerOrdersDispatcher.cs</a>. </p> <p>You may view the full sample application source code as well to see how it works out: <a href="https://github.com/tugberkugurlu/AdvancedWebAPI/tree/master/PerRouteMHOwnershipSample" rel="noreferrer">https://github.com/tugberkugurlu/AdvancedWebAPI/tree/master/PerRouteMHOwnershipSample</a></p>
