Notes

Initially the plugin was using the jQuery .load() functionality. It has been however removed, because it doesn't load any scripts.

http://api.jquery.com/load/

"jQuery uses the browser's .innerHTML property to parse the retrieved document and insert it into the current document. During this process, browsers often filter elements from the document such as html, title, or head elements. As a result, the elements retrieved by .load() may not be exactly the same as if the document were retrieved directly by the browser."

"If .load() is called with a selector expression appended to the URL, however, the scripts are stripped out prior to the DOM being updated, and thus are not executed."
