At each page, you could do something like:
$_SESSION['trail'][]=$_GET['ProductID'];
When they hit the back button, I believe that some browsers will
actually add another entry into the array, so you might have something like:
.... 13, 45, 13 ...
Indicating that the user was on page 13, then clicked to 45, then hit
the back button. Watch out though, many people like to open multiple
windows (or tabs) when browsing, so that will give you some pretty awful
results.
