Tracking page referrer on first page view of a visitor in rails app

Question

Hi,

I want to be able to read the referrer of visitors coming from certain domains when they come to any subpage of a rails app.

How would I handle that before the controllers come into play ? (I want a general solution for alle pages, not to check it on every single controller)

Any hints appreciated.
