checking.php

$referrer = $_SERVER['HTTP_REFERER'];
if (!preg_match("/redirect.php/",$referrer)) {
    echo 'not redirect from redirect.php';
}
else
{
    echo 'is redirect from redirect.php';
}

redirect.php

Using header("location: http://abcdomain.com/checking.php");wont set REFERRER, one possible solution is shown below(tested and works 100% fine)
USE THIS IN REDIRECT.php 

echo "<script>parent.self.location='http://abcdomain.com/checking.php';</script>";
exit();

This will set $_SERVER['HTTP_REFERER'] in checking.php


Possible Reasons for this problem shown below

Some browsers limit access to not allow HTTP_REFERER to be passed
Type a address in the address bar will not pass the HTTP_REFERER
open a new browser window will not pass the HTTP_REFERER, because HTTP_REFERER = NULL
has some browser addon that blocks it for privacy reasons.
Some firewalls and AVs do to.

Is it not redirecting at all for you, or redirecting, but printing the wrong message? If it's not redirecting, try "Location:" upper-case.

It if is redirecting try var_dump($_SERVER); to see what is in it.
