How to send traffic to a certain page first time and if they hit back button to other

[jasonst78]

Hi everyone,

I am wondering if there is a way to implement something into this code that; (1) if the referer is set properly from google.com, it will always send the initial traffic to http://mysiteA.com; (2) but when the back button is pressed it will send them to the other links besides http://mysiteA.com.

<?php
$ref = $_SERVER["HTTP_REFERER"];
if (strpos($ref,'google.com')!==FALSE) {
$urls = array
("http://mysiteA.com",
"http://mysiteB.com",
"http://mysiteC.com",
"http://mysiteD.com",
"http://mysiteE.com");
 
$url = $urls[array_rand($urls)];
 
header("Location: $url");
}
?>

Hey.

Not really no.
You have very little control over what the back button actually does. Some browses may send the exact request they did before, making it look as if you just came back from Google, and some might do it as if you had pressed a link from your current page. Some might even just skip the referrer altogether.

You could try using sessions or cookies to track the user's movements, but that might be tricky over multiple domains.
