Specify the instance of a PerWebRequest component at runtime in castle windsor

Question

I currently work in a asp.net MVC Web Api project using castle 3.1.

I registered a component with a lifestyle 'PerWebRequest'.

I would like to manually tell castle which instance to use instead of letting the container create the instance. On each web request.

Here's how I achieve this:

I cache the HttpRequestMessage instance in the HttpContext's Items collection via a DelegatingHandler(for those who don't know, DelegatingHandler are first extension point offered by the WebApi framework). When registering my component, I use a factory and retrieve the HttpRequestMessage from the context.

Here's the code:

public class InjectingCurrentHttpRequestHandler : DelegatingHandler
{
    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        HttpContext.Current.AddHttpRequest(request);

        var output = base.SendAsync(request, cancellationToken);

        HttpContext.Current.RemoveHttpRequest();

        return output;

    }
}

Here's how I register my component:

container.Register(Component.For<HttpRequestMessage>()
                            .LifestylePerWebRequest()
                            .UsingFactoryMethod(() =>
                            {
                                var context = HttpContext.Current;
                                if (context == null)
                                    throw new Exception("HttpContext is null. Resolving HttpRequestMessage can only be done during an http request. Have you forgot to add the '" + typeof(InjectingCurrentHttpRequestHandler).Name + "' handler in the framework?");

                                return context.GetHttpRequest();
                            }));

It does work but I would like to avoid using the HttpContext.Current instance. Is there a better way to achieve this using castle?

I feel like the support for this should be built-in castle, but can't find it.

Thank you,
