/* Records a user's download action with SalesForce using a SalesForce custom object, "Download".
category: Download Category
href: Download Item
redirect: boolean; should the page relocate to the href upon completion?

note: The redirect was necessary because of the nature of the ajax request.
The 'recordDownload' action is being used in the onclick attribute for links in the site.
If the onclick allows the link's href to be followed (does not 'return false'), then the 
ajax object is 'left hanging' as the browser navigates onward.
(I believe this may only be an issue with links to non-html pages, such as PDF files.)
