detect referral url and redirect/popup window

[miniajuer]

hi i was wondering if there is any script that could pop up different content window for different refferal links.
like if site1.com sends me a visitor to mysite then page1.php pop's up
and if site2.com sends me a visitor to mysite then page2.php pop's up??
is there anykind of script???

can anyone here help??​

In PHP as an example, which should be much larger than this.

if($ref=='site1') header("Location: page1.php");
