The Dispatcher

The dispatcher is actually to about 80% the work of friendlyGIS ®. However, we used a small Webserver application known as "personal WEB Server" as a starting point. Here is the copyright message from the parts of our SWL-Dispatcher code which still contains parts of the original:

** This code covers a system derived from the "personal web server"
**
** Copyright 1997 Clay Lenhart

** from which the framework covering the management of web server
** requests has been taken with quite a lot of modification.
