I'm not sure exactly what you mean by code reuse in this context. When you
specify an error page using CFERROR with types VALIDATION or REQUEST, those
pages can't have any server-side code in them. However, they can be invoked
by any page within your application that encounters those error types.
You can also use client-side code in those pages, such as _javascript_. Years
ago, we used to use _javascript_ to capture error variables and redirect the
error to another server-side script which could then do something with that
error data. Of course, this is a relatively fragile thing to implement, and
we don't bother with that sort of thing any more.
Nowadays, if you want to execute server-side code in response to an error,
use TYPE="EXCEPTION" and/or the site-wide error handler. The REQUEST error
page should be the error handler of last resort, only being used if all your
other error handlers have failed. The VALIDATION error page should only be
used if you're using the built-in server-side validation rules, which I
would recommend that you not use in any case - it's not really server-side
validation, and isn't reliable for validation for security's sake.
