Hi -

I need to see what page a request came from in my controller so I could be able to redirect back to it. For example, if I'm on a page showing a specific product (say /products/1) and it has a link to its vendor (/vendors/12), I want to be able to detect inside the vendors_controller that I came to that page from /products/1. Is there a simple way in Rails to achieve this, so that I could access it via params or session? thanks.
