Code execution for each request

Question

I want to be able to execute some code for every request that stores data in ViewData. I currently have a base controller class that inherits all my controllers, and I override OnActionExecuting and do it there.

My only concern with this approach is that whoever ever creates a new controller HOPES to inherit the form of the base class.

Is there a way to register something in global.asax, as with custom model bindings that will trigger each request? Kinda as a global action filter or something like that.

Answer 1

Instead of using the base class of the controller (which, in my opinion, is the best option for most scenarios), you can use a custom action invoker , I would get from the built-in action invoker and sprinkle extra things that you need. You register an invoker action during application startup in global.asax and you can override OnActionExecuting / OnActionExecuted / OnResultExecuting / OnResultExecuted. For example, you can use OnResultExecuting to add to some ViewData. At this point, you will find out that the action is complete, and also recognize the type of ActionResult.

Answer 2

In global.asax you can add a handler to the Application_BeginRequest , which runs before each HTTP request. You can also create a custom HTTP module to handle the same.
