Rails - Jan 2006 - Redirect to where I was

I wonder if there is a standard Rails way to redirect from an action
back to a previously viewed page. As a quick fix I created two little
methods in the controllers/application.rb. Does this seem like an ok
way to go?

Thanks,
Peter

class ApplicationController < ActionController::Base

  def i_was_here
    session[:i_was_here] = request.env[''REQUEST_URI'']
  end

  def redirect_to_where_i_was
    redirect_to session[:i_was_here]
  end

end

One of the login systems used a similar approach.  You could even add a 
before_filter on certain actions to run the ''i_was_here''
method
automagically.  You do run the danger of having a 
redirect_to_where_i_was go back to itself, thus creating an infinite 
loop.  You might want to do a little checking to make sure the current 
location and the target location aren''t the same.

There''s also:

  redirect_to :back

but bear in mind that it will only work if you got to the current page
by actually clicking a link (i.e. where your browser gave some referer
information)

Why use session?

   class ApplicationController < ActionController::Base
     def i_was_here
       request.env[''REQUEST_URI'']
     end

     def redirect_to_where_i_was
       redirect_to i_was_here
     end
   end

But...what''s this about???

   redirect_to :back

If you use a session, the place you go back to can be 3 or 4 pages 
earlier and/or set programmatically.
