How to get request referer path?

I need the 开发者_如何学Cpath of the referrer. I don't want the domain name. For example, if the referrer is http://www.google.com/adsense I want /adsense.

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'

You can access referer with

request.referer
