I suppose the "best" solution would be to duplicate the cacheability
information from the document being validated. This problem could also be
fixed by making the referer script send a 303 (or maybe 302) response
redirecting to the check script with the URI in the query string. As a
workaround, you can use the "Revalidate" button.
