The JavaScript Source: Cookies : Cookie Redirect

General

Redirects the visitor to different pages based on the value of a stored cookie. If no cookie is found, the available items are displayed for the user to pick from, which sets a cookie for their next visit.

(Choose an animal then reload the page to see how the redirect works.)
