Using cookies to display a landing page to new visitors only
I've just had a request to set up a landing page that only new visitors to the site see. I'm assuming this is the sort of thing that can be done with cookies, but not sure how to set it up.
I've gotten as far as creating a test page, with set a standard cookie called 'landingpage'.
I assume I need to somehow set it up so that it checks the cookie, and either displays the landing page, or redirects to a different page.
If its possible, and not too tricky, I'd be really grateful for some pointers.
