Preparing a document for transmission over a network in a manner that increases the security of URLs included in the document. A server accesses a document that contains a number of URLs. For one or more of those URLs, the server calculates a digital signature that is unique to the intended recipient client, or unique to the user of the client. The server then modifies each of those URLs by including the digital signature in the URL. The document with the modified URLs in then transmitted over the network to the client. Thus, even if a sensitive URL is discovered, that modified URL is unique to the client only or to the user of the client only. Therefore, the damage that may be caused by an unauthorized user is limited to just that client or user.

Methods and systems for using digital signatures in uniform resource locators

Methods, systems and computer program products for tracking a client's usage of one or more services provided by one or more servers. A client generates and sends one or more metering packets to a census service. Each metering packet includes a time element indicating the client's usage of the one or more services. The time element may include a charged time portion and a free time portion. An authentication element may be included with each metering packet so that the census service can determine whether or not a given metering packet is genuine. A login service communicates to the client whether or not usage should be tracked and indicates a time interval to expire between subsequent metering packets. A session identifier in each metering packet allows multiple sessions to be tracked simultaneously. Upon receiving metering packets, the census service discards redundant metering packets and updates a usage database accordingly.

A lightweight row transfer protocol is described that can be easily handled by thin clients, such as JAVA&#x2122; applications using CORBA. The lightweight row transfer protocol serves to reduce bandwidth requirements by applying compression techniques to reduce the number of column lengths in a 'result set' of rows that are transmitted from one computer to another.

Lightweight data replication

Replication for front office automation involves the use of snapshots that are instantiated on laptops, in which refreshing the snapshots is driven from a master site with a high-performance protocol. All of the necessary snapshot metadata for performing the snapshot refreshes is stored at the master site, so that the laptop only needs to send a single refresh request. In response to the refresh request, the master site reconciles the differences between the master tables and the laptop's snapshots and transmits the differences to the laptop, reducing the necessary network traffic for updating a snapshot to a single round trip.

A drain plug sensor for determining whether a drain plug is inserted into a drain hole of a watercraft is provided. In a preferred embodiment, a reed switch for sensing a magnetic field is threadably mated with a receiver at one end thereof. The receiver and reed switch are emplaced into the drain hole. The drain plug, which is capable of being inserted into another end of the receiver, is formed together with a samarium cobalt magnet such that a magnetic field is created and emanated therefrom. In this manner, whenever the drain plug is inserted into the receiver, the reed switch detects the presence of the magnetic field. Conversely, whenever the drain plug is not inserted into the drain hole, no magnetic field is detected. Regardless of whether the drain plug is inserted into the drain hole, an indication is supplied to a user to alert the user as to whether the drain hole is operational.
