Caja and JQuery

开发者_如何学PythonSuppose I use the cajoler to sanitize third party javascript and run it in a host, and regarding JQuery:

• Can the third party application include JQuery, which will be cajoled in the process, or,
• Does the host site expose JQuery functionality to the third party?

The third-party application should reference jQuery itself. If the host page were to provide jQuery, then that copy of jQuery would have access to the host page DOM, so the third-party application would not be properly confined.
