JANOS supports a highly capable WebServer which can handle multiple
connections from multiple clients simultaneously. Both non-secure (HTTP)
and secure (HTTPS) connections are possible for pages served publicly and
those requiring authentication.
A Hypertext Preprocessor modeled after PHP is available providing the
ability to create dynamic and fully-featured websites. This general purpose
scripting language is also uniquely available for program and batch file use
in the Command Line Console environment.
Each WebServer connection can be dynamically upgraded to support the
Websocket protocol providing full-duplex general-purpose communications with
JNIOR. By default a Websocket connection supports the JANOS Management
Protocol (JMP), a rich JSON based message exchange capable of all aspects
of product administration. This includes file transfer, command line console
access, Registry manipulation and I/O control and monitoring. In short, the
entire product can be managed through a single HTTP/HTTPS connection.
Inter-process communications are provided allowing an Application Program to
be written as a network server. Custom protocols are then possible and
proprietary protocols can be accommodated.
Finally, uniquely the JANOS Webserver can serve an entire website directly
from a single ZIP library file. This incredible feature allows the website
to be installed and updated as a single file eliminating any risk that
files may be missing or go out of sync. For example the entire default
WebUI is contained within the /flash/www/config.zip file. This file need
never be expanded.
The default WebUI demonstrates the power of the JANOS WebServer. These
dynamic configuration pages leverage the power of the Websocket connection
and the strength of the JMP protocol.
