Function
Url prefix of the site which can handle JSONP requests.
This allows for adapting HTTP requests that could not otherwise be sent with JSONP, so you can use a convention for headers and PUT/DELETE methods.
Adds the script transport (JSONP) as an XHR plugin for the given site. See dojox.io.script for more information on the transport. Note, that JSONP is *not* a secure transport, by loading data from a third-party site using JSONP the site has full access to your JavaScript environment.
