The above code will redirect to the pages in round robin fashion. p2->p3->p4->p5->p2->.. so on until they reach the limit.

Is this correct implementation? Any other better way to do?

Looks good. I think random number generation more appropriate. Say if rand() returns a floating point numbers between 0.0 to 1.0, if (0.1 <= value < 0.15) we redirect to p3.html and so on. In your case, there will be a situation when user will refresh p1.html 65 times before he skips p5.html.

//Calculate a random number between 0-99;
var random = Math.floor(Math.random()*100);

if(random >= 0 && random < 10) {
  //redirect to p2.html
}
else if(random >= 10 && random < 15) {
  //redirect to p3.html
}
else if(random >= 15 && random < 35) {
  //redirect to p4.html
}
else {
  //redirect to p5.html
}
