The world of subject directories and search engines is a highly volatile one. Don't be dismayed if you search leak detectors,and discover that things have changed. This is part for the course. Many of these sites are commercial enterprises and competition is keen. When changes occur, they are often for the better as the service attempts to keep ahead of the pack. Enjoy the ride!
The World Wide Web provides a single interface for accessing leak detectors. This creates a convenient and user-friendly environment. It is not necessary to be conversant in these protocols within separate, command-level environments, as was typical in the early days. The Web gathers together these protocols into a single system. Because of this feature, and because of the Web's ability to work with multimedia and advanced programming languages, the Web is the fastest-growing component of the Internet.
