class HTTP::ErrorHandler

Overview

A handler that invokes the next handler and, if that next handler raises an exception, returns with a 500 (Internal Server Error) status code.

In verbose mode prints the exception with its backtrace to the response. Otherwise a generic error message is returned to the client.

This handler also logs the exceptions to the specified logger or the logger for the source "http.server" by default.

NOTE To use ErrorHandler, you must explicitly import it with require "http"
