Handles HTTP exception e which was thrown while parsing the request message or from handleRequest() or request_msg_body_length(). A subclass may override this method to be notified when an exception is thrown and decide whether the connection may stay persistent or should be closed after the response has been sent. The default behaviour is allowing the connection being persistent unless the status code indicated by the exception is 413: "Request Entity Too Large".
