I have read articles that give various ways to do "URL masking" so that the browser's URL bar does not show the actual location of the content. Such methods include setting up an .htaccess file, showing content in an iframe, or loading content from another source with javascript.
The problem with all of these methods is that the URL shown in the browser can actually be used to view the content I want to protect, even though it's coming from another location.
I need a way to have the browser display protected content while the URL bar displays a URL that will NOT show that content, because I don't want a person who has been given access to the content to be able to share access to that content by giving the URL away to others.
Is this possible?
