As the JadeHttp library or the JADE mod_ jadehttp module can communicate via a TCP/IP connection to a different workstation running the JADE application, you can ensure that the JADE environment is entirely behind the firewall. In the default implementation of the JADE Internet environment, the JADE application writes image files directly into the virtual directory for subsequent Web browser access.
Files transferred by a Web browser to the JadeHttp library are written into a directory for access by the JADE application.
Use of a firewall requires that there are no network directory services running between the Web browser and JADE environments.
The only available links are TCP/IP connections. JADE applications do not write files directly into the virtual directory outside the firewall. Instead, the files must be passed via the TCP/IP connection to the JadeHttp library, which creates the file in the virtual directory. Similarly, files arriving at the JadeHttp library from a Web browser are passed to the JADE application via the TCP/IP connection.
The JADE application writes these files into the JADE Web application directory.
