Each of the siteclasses, the network-library and the main-class library can implement handlers for various web-site situations.

Such as "file not found", "user was denied permission", "login failed". Using these handlers every part of the user website experience can be customized. It should be possible to build sites that bear little or resemblance to each other. This is in contrast to Xoops, Tiki etc. that all share a common easily identifiable look and behavior.

There is a file for each one in MAIN_CLASS_DIR/handlers
