Choosing a Secure Communication Protocol for Configuration File and Codebase Downloads

There might be unauthorized personnel listening in on your application’s network traffic. While detecting such eavesdropping is not easy, you can make the eavesdropper’s job much more difficult by encrypting application configuration file and application-component downloads — which you can do by using a secure communications protocol. An example of such a communications protocol is HTTPS, which encrypts network traffic using a combination of symmetric and asymmetric ciphers. (For more information on symmetric and asymmetric ciphers, see the "Digitally Signing Files" section).

NOTE: If application components to be downloaded reside on an AppServer and you select the HTTPS protocol (or the HTTP protocol) for application-component downloads, you must use the AppServer Internet Adapter (AIA).

For more information on choosing a communication protocol for application configuration file and codebase downloads, see Designing the Deployment Configuration." For more information on the HTTPS protocol and the AIA, see the “Appserver Internet Adapter” chapter in the Progress Version 9 Product Update Bulletin.
