Rails - Aug 2006 - How to retrieve :web when redirecting to an Instiki page?

Hello, I am currently working on implementing some authentification code 
onto Instiki (0.11.0). I am encountering a problem in this situation :

When I try to access say http:/localhost:2500/orz/show/Test , where orz 
is an instiki web name, I am redirected to my signin form screen (which 
is what I want) but then upon signing in I get the following message:

No url can be generated for the hash {:controller=>"wiki", 
:action=>"show",             :id=>"Test"}


Now if I then type in http:/localhost:2500/orz/show/Test in my browser 
addressline I can access the page without any problem. So there seems to 
be a problem with the redirection in my signin method, which looks like 
this:

def signin
ession[:user] = User.authenticate(params[:username], 
params[:password]).id

redirect_to :web=> session[:intended_web],
            :controller => session[:intended_controller],
            :action => session[:intended_action],
            :id => session[:intended_id]

end

I realize that session[:intended_web] is a naive attempt and returns nil 
since that session variable doesn''t exist, so how should I go about 
retrieving the intended web''s name upon signin redirection?

(Of course if there is a single web and I set DEFAULT_WEB to the web''s 
name, as well as setting :web=> DEFAULT_WEB in the signin method, there 
ceases to be a problem, but I would like a solution that works with 
multiple webs.)

Any help is very appreciated.
