Asp.NET error screen's HttpModule

Guys, what is the name of HttpModule which serves standard Asp.Net error screens with the stack trace? Can I disable this in order to modify response when application error occurs? Or is there another way to modify the response for example in Global.asax or custom HttpModule on Applicat开发者_开发百科ion_Error?

Why don't you use much better CustomErrors section in web.config
