Rails - Aug 2006 - setting a session variable, :value and :session_path

Hello,

I''m having some difficulty with using sessions.  Basically,
I''d like to be
able to store a hash in an action:

def action
  session[:details] = {:value => some_hash, :session_path =>
"/main"}
end

I''d like to be able to retrieve the hash in another action under the
same
"main" controller.  I retrieve it by doing the following:

def action2
  hash = session[:details]

  v1 = hash[:name]  # Problem is that this is null
end

I''m not able to get my values out as I expect.  Any help would be
appreciated.  Also, when I set :session_path => ''/main'',
does this mean that
the session[:details] will get nulled if a user were to get out of the
"main" controller path?

Thanks.
