title: Injecting global ActionFilter to existing ASP.NET MVC application
body: <p>For an ASP.NET MVC COSTS application, I need to intercept all action calls. I only have access to modify the <code>global.asax</code> and <code>Web.config</code> files since it's already compiled and I have no access to the source code. Am I out of luck on injecting a global action filter to it?</p>
