Cascade HTTP is a JDK 1.0.2 based Web Server by David Wilkinson. It was written many years ago when Java was in its infancy as a demonstration of how Java could be used on 'non-trivial' projects. Since then, much has happened in the Java world, and the popularity of Java has boomed. Cascade HTTP turned out to be a great success - far more people downloaded it than I ever thought would be interested, and many of them have found it useful.
