I need the path of the referrer. I don\'t want the domain name. For example, if the referrer is http://www.google.com/adsense I want /adsense.
http://www.google.com/adsense
/adsense
You can access referer with
request.referer
request.referer returns a string, but you can use Ruby's URI Module to wrap it and then simply ask it for its path:
if URI(request.referer).path == '/adsense'
