Definition - What does Jigsaw mean?

Techopedia explains Jigsaw
Jigsaw 2.0 is designed for technology demonstration purposes; it is not a full-fledged, ready-to-use web server. It is designed as a project to portray new technology advancements for future HTTP and object-oriented web servers.
Jigsaw is written in Java programming language, which is designed to work in an object-oriented framework. Java programming language is used in almost all new-generation web servers. As such, it works with all operating systems that support the Java development kit. Jigsaw has been implemented successfully on Windows 95/98 NT, Windows 2000 and Solaris 2.x, but it also works on AIX, OS/2, BeOS and Mac OS. The use of Java programming language to develop Jigsaw allows it to be used across server platforms.
Although Jigsaw is intended for the demonstration of new technologies, W3C reports that it works well as a CERN server and also supports features like proxy server, virtual hosting and common gateway interface. Jigsaw can also be used for designing pages built on PHP and JSP scripts.
