admin:appserver-set-error-handler( $config as element(configuration), $appserver-id as xs:unsignedLong, $value as xs:string ) as element(configuration)
This function sets the value of the path to the error handler in the configuration for the specified App Server. The path should specify a relative or absolute path to an XQuery module that is executed in the event of any 400 or 500 series HTTP errors (sometime known as a "sorry" server to give the user a clean error page).
