This is a simple problem but I expect has a very difficult solution.
I want to have a page run some PHP code on http request, without using mod_rewrite and without using javascript.
ex. http://website.com/some_audio.mp3 when user or robot requests this link, a php script is called to process and then deny or allow the request.
I cannot use mod_rewrite for this, I know it sounds crazy just take my word for it. Also cannot use javascript either since robots would bypass this. need some kind of htaccess solution.
