Hi, I have a page (A) that contains a table with links in one column. When the user hits a link it goes to another page (B) which is a read only form page with a done button. This page (B) is being reused in various parts of the app read pages (C) and (D). Thus when the user clicks 'Done' it needs to return back to where she comes from ie either (A), (C) or (D). I thought with the new Rails 0.14.3 I could just do redirect_to :back and all my ills would be cured. But.... this redirects me back to where I currently am ie (B). I am sure this is a very common problem out there. In my java life I would create something in the session and consume it when this exact situation arises. Is there a magic rails spell that I could use for this situation ? I am not sure how to get the URL of page (A) so I can stach it in the session for later retrieval or somehow push both the controller and action of the page where the request was originated (??) Sample code please... Thank you all !!

Then once they finish with that page you call redirect_back_or_default to send them to the location stored in the session.
