detect mvc controller and API controller request through HttpApplication

Question

How to detect that incoming request is for MVC controller or API controller through HttpApplication?

Answer 1

There are different ways to achieve what you want. Assuming you´re working with ASP.NET MVC 4+ you could use:

Application_BeginRequest()

You can register this Event in your Global.asax.cs

For example you could access your request like so:

    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        //Perform actions on HttpContext.Current.Request
    }

You can find a pretty nice overview on this event here (DotNetPerls Example).

Another possible solution would be a GlobalFilter. This was already answered many times and you can get further information Here (Stack Overflow Answer).

It depends on your use case what version you would prefer.
