What's the best to add my own error handler? I see there is some processing based on *SHOW-LISP-ERRORS-P* *SHOW-LISP-BACKTRACES-P* inside process-request function, but it doesn't allow to add a user handler of the error (or I just didn't find it). Let's say I don't want a user to see the error (only some nice reassuring message :)) and I want to be notified by an email with the backtrace. Should I go and modify the body of the process-request function (which I'll need to merge with every new release of HT) or is there a way to add my own handler outside of the Hunchentoot code?
I've generally found it enough to define error handlers just like I usually do in CL:
(defun foo () "Display the foo page" (handler-case (... faulty code which might produce some error ...) (error () (display-a-nice-error-message))))
