Handles HTTP server exception e which was thrown while parsing the request message or from handleRequest() or request_msg_body_length() and is not a HttpException. 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 to stay persistent.
