The $HTTP_REFERER variable is not always set properly by all browsers, so beware if you're
writing an application that depends on this! For example, the @home browser erroneously sends
garbage when there is no referer. Also, my AOL customers tend to have problems with the referer,
depending on which version of AOL you're running. So, if you want to protect your site (or
content) by allowing only "registered" links to you, don't depend on the HTTP_REFERER
