javascript redirect based on referral url

[ztik]

I used to have this code, I tried recoding it myself but I suck, google also sucks

Anyone have this code handy?

If ref url = aol.com then newurl=google.com

this is kind of close

if (document.referrer != "") {
var referringURL = document.referrer;
var local = referringURL.substring(referringURL.indexOf("?"), referringURL.length);
location.href = "http://page.com/login" + local;
}
