Answer 1

I believe you can with an action filter.

Try this article.

Answer 2

You can do it in Global.asax.cs for all requests by

protected void Application_BeginRequest(object sender, EventArgs e) {
   //Look at HttpContext.Current.Request to grab request values 
}

Model binding occurs before action filters run. If you want to write a filter that runs before model binding, you could write an IAuthorizationFilter which runs before model binders.
