redirect_to an uncertain hash

I am trying to deal with a redirection based upon what to do after a session has expired. I take the params hash and stuff it into a new session as part of the new login and then after login, I want to redirect to this hash as though they were params again...

Thus I start by setting   session[:direct_to] = @params

And after I login, I want to redirect based upon the values in session[:direct_to]...

What I am trying to do is this but I keep getting syntax errors...

     redirect_to (session[:direct_to].each do |key, value|        "#{key} => #{value}"        end)

Of course there are values that are obvious such as session[:direct_to][:controller] session[:direct_to][:action]

but there are a lot of other params that may or may not be included so I am trying to abstract and recover them in my redirect_to statement. Is there a way that I can do this?


rather than store the params hash in the session, why not just store
the actual redirection url?

session[:direct_to] = url_for(params)

redirect_to session[:direct_to]
