[UPHPU] throttling bots and spiders

well one idea could be using a mix of a xmlhttpquest object and php. you
would have to rely on the users interaction to trigger the session though
when they visit the page, possibly an OnClick(). That would assure it was a
real user who visited ( because they physically clicked the page.)  It might
be handled with <body OnClick="CheckSession();>. Checksession would
determine whether the user has clicked the page once or not. you probably
will have to have some kind of variable counter to stop the check after 1
click, because you don't need to keep checking the body with every click. Or
you could just reload the page with a header() to not include the
checksession after the session is assured valid. just some ideas.
