Tracking UPS Packages via JavaScript
/**
* A post at TechDigits [https://web.archive.org/web/20050311025802/http://techdigits.blogspot.com/2004/12/ups-package-tracking-with-rss.html]
* about tracking UPS packages via RSS and web services got me thinking if the same is possible via Javascript and
* the XmlHttpRequest object (in IE and Mozilla). Since Google's Gmail and Google Suggest started using that object,
* it has become more popular. So after some thinking, I put together the following quick and dirty code snippet
*
* I don't know how useful this can be since the security information is exposed, but it is a nice hack.
