Question

Let’s say I have a RoR app with 3 pages.
The user can get to page 3 via a button on page 1 or page 2.
On page 3, how can I track where they came from – so I can send them back to that page?

Thanks

I think there are three solutions.

First, store the previous page url in the session. See: How to save http referer in rails

Second, store the url in params of get request. For example, the button will on page 1 look like this: link_to "page 3", "/page3", :ref => "page1"

And third, use http referer already answered by @johnernaut
