The RAP Protocol is the JSON-based format used within the HTTP-Requests from a RAP-client to a RAP-server. Compared with the previously used JavaScript and HTTP-fields based communication is will provide a number of advantages:

  • It allowes to move all client-specific code from the server to the client.
  • It produces human readable messages, easing debugging.
  • It allowes the client to create more informative error messages.
  • It allowes to replace either ends as long as they process and create valid RAP-protocol messages.

The protocol is currently beeing developed in CVS HEAD. While not fully implemented, the communication will be mixed between old and new format, e.g. JavaScript-code with embedded JSON-objects. We expect to fully switch to the new format (at least the client-to-server direction) with the 1.5 release.
