Page that will only open if it comes from a redirect (Looking for a way to do this)

[vandiermen]

My problem is that I want to give people an address that they can not give to other people! And I don’t want to create a login system, what I am looking for is a page that redirects to an other page that can only be opened if it has been opened by the redirect before it. I am thinking there may be some java scrip for this or something.

I would also be interested in a way to make a page change its name
e.g.
http://www.test.com/privrgxergergergatrgerg.hcgl
as soon as someone hits the above address the address changes to:
http://www.test.com/private.hcgl (and private.hcgl dose not really exist or is something else)

You can set a session on the redirect and then test to see if it's set on the final page. PHP would be a much better way to do this, however.
