The communication is done on a file basis. Thus the system is set up very easily.

The be.as server communicates via HTTP with the PHP connector

6. © beas2012 / Page 6 BEAS- Server Client Web- Browser Lokales Netzwerk 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. External PHP- Server Firewall

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. External PHP- Server Only text files, max 512 KB CSS-, JS-files images, 2 GB or more Connection speed

8. © beas2012 / Page 8 BEAS- Server (beas als Windowsdien st oder als separater Server-Task) Client Web- Browser 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. Externer HTML- Server Query interval 500 ms Query interval 100 ms Answer times

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) Externer HTML- Server Passwortschutz Firewall Security

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.

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) MSSQL-Script
