 By default, Spring Boot provides an `/error` mapping that handles all errors in a sensible way, and it is registered as a "`global`" error page in the servlet container.
 For machine clients, it produces a JSON response with details of the error, the HTTP status, and the exception message.
 For browser clients, there is a "`whitelabel`" error view that renders the same data in HTML format (to customize it, add a `View` that resolves to `error`).
+
+There are a number of `server.error` properties that can be set if you want to customize the default error handling behavior.
+See the <<appendix-application-properties.adoc#common-application-properties-server, "`Server Properties`">> section of the Appendix.  
+
 To replace the default behavior completely, you can implement `ErrorController` and register a bean definition of that type or add a bean of type `ErrorAttributes` to use the existing mechanism but replace the contents.
 
 TIP: The `BasicErrorController` can be used as a base class for a custom `ErrorController`.
