Now, what was I just saying?

via Ajaxian:

Cody Swann was working on a web application that was using the Dynamic Script Pattern, which Dojo has excellent support for, but Prototype didn’t.

Cody then extended Prototype to support ScriptSrcTransport similarly to how Dojo does it.

The code below support the Simple, Polling and JSONP and JSON Callbacks described in the Dojo book.
