Is there anyway to grab the referring URL using javascript, lets say the reffering url is http://page.com/home?local=fr, then redirect a user to a new page with the same local as the reffering page (http://page.com/login?local=referring local)?

Pseudo code would be something like this:

var referringURL = document.referrer;

var local = referringURL.substring(referringURL.indexOf(?), referringURL.length())

var newURL = http://page.com/login +local;

Send user to newURL
