Post Message

PostMessage is a simple text-based messaging format that is compatible with the way HTML Forms are posted back to the server via HTTP.

Use Cases

While not really useful in production scenarios, PostMessage makes it easy to post data directly from a HTML form to a service by simply specifying the service url as the Action attribute.

You can also use PostMessage when you need a simple human-readable messaging format - for example for debugging or monitoring purposes. In this case, you might also want to consider XML-RPC Message.
