Construtor/Setter Injection using IoC in HttpHandler, is it possible?

Question

I\'ve ran into a rather hairy problem. There is probably a simple solution to this but I can\'t find it!

I have a custom HttpHandler that I want to process a request

Answer 1

What you could do is have the HttpHandler call out to another object that actually handles the request. so in your HttpHandler's ProcessRequest method you would do something like this:

public void ProcessRequest(HttpContext context)
{
 var myHandlerObject = container.Resolve<HandlerObject>();
 myHandlerObject.ProcessRequest(context or some state/info that is required)
}

Answer 2

Not possible, at least not directly. IHttpHandler objects are instantiated by the ASP.NET runtime and it doesn't allow Windsor to get involved in its creation. You can either:

• Pull dependencies, by using the container as a service locator.
• Set up a base handler that creates, injects and delegates to your own handlers (see how Spring does it)
• Use the container as a service locator for another service that handles the entire request (as saret explained)
