Just be aware, that the referer can be forged fairly easily - don't rely on it for any kind of security or authentication. Basically, never trust the client (in this case, the browser).

I have noticed how some websites only allow access to a particular page if a link within the page has been 'clicked' ie. user cannot paste link address in browser bar to get to desired page. For security purposes I would like to create a script and achieve similar results.
I believe that (at least one way) this is done is by checking the referer header. In PHP this can be accessed via the predefined variable: $_SERVER['HTTP_REFERER'], other languages should have similar methods of obtaining this. AFAIK, there is not a difference between HTTP and HTTPS as far as this method is concerned. -- Jason
