Requests to p1.html should result in 10% of users being redirected to p2.html, 5% of users redirected to p3.html, 20% of users redirected to p4.html, and 65% of users redirected to p5.html. 5. Users do not need to stick to the page they are first redirected to. They could end up on a different page with every request to p1.html 6.
