Webpage Redirect Rotator - Redirection url changes each time a unique visitor returns

To design a script that will redirect visitors to different url's, based on how many times they have visited a landing page. Example: User1 goes to my html landing page [login to view URL] or php landing page, if required: [login to view URL] They will then be automatically redirected to a different url, with no interaction required by them FIRST VISIT: On their 1ST visit, they are automatically redirected to [login to view URL] SECOND VISIT: On their 2ND visit, they are automatically redirected to [login to view URL] THIRD VISIT: On their 3RD visit, they are automatically redirected to [login to view URL] and so on. (Up to 6 redirects). Note: I am not looking for a random redirect or a redirect script that will show each url a certain percentage of time. Each unique visitor MUST go through the same sequence, starting at URL1 and progressing through the next url on each subsequent visit. I assume this will be achieved through cookies? Thanks
