BEASServer
(beas as

or as separate
Server-Task)
Requires an arbitrary PHP server. be.as automatically installs a PHP Connector
(small PHP file) and uses a directory for communication with the BEAS-server via PHP
connector.
The communication is done on a file basis. Thus the system is set up very easily.

If a local web access is not desired or not allowed for safety reasons, the PHP connector will
be installed on any web server. The be.as server communicates via HTTP with the PHP
connector

Firewall

A firewall blocks external access on the local server in a network.
That why it is impossible, to tap data from the local PC.

BEASServer
Usually a firewall operates only one-directional: incoming requests are blocked. Therefore, we
use indirect communication: The client sends a query to the external HTML server, the be.as
server asks, if there is a query and retrieves them, returns a response and the PHP server
passes that response back to the client.

In the local network, the upload speed is 512 KB. When uploading images, large JS
and CSS files, the line is overloaded quickly.
Everything that can be outsourced, images and other media files as well as large-JS
and CSS files, are stored directly on the external server.

Query interval

The be.as server checks every second whether a client request exists. If so, it
is processed and a response is returned. The HTML server is queried at 100 ms
cycle for a response. In total, there is a theoretical maximum response time of
0.8 sec + setup time of the web pages.

BEASServer
Communication with HTML server is password protected. The indirect
communication is very secure, there is no need to open the firewall.
Data is received and sent unencrypted. If a higher security is required, establish a
local network (VPN)

BEAS.EXE
In be.as a WEB-application can be created with be.as-Script, JavaScript or HTML.
Basic language is be.as-Script, the application runs in a beas screen, the complete
functionality of beas is accessable. The surface on the Client-Web-Browser is defined
in the WEB-program.
This makes HTML-objects available, which assist in the creation of surfaces.

Basic language is beas-script, extended by a HTML-object, which makes available several
useful tools.
There, JavaScript, HTML, MSSQL and PHP can be used. Programming languages can be
mixed (as in classical PHP-development, based on BEAS-Script instead of HTML)
