Rails - Jun 2005 - method finishing processing even after encountering a redirect

At the beggining of one of my methods I have the following code:

         if session[:id] == nil
             session[:jump_to] = @request.parameters
             redirect_to :controller => "sign_up"
         end

I expect that when if evaluates to true that the rest of the method  
will not be executed but it seems to be.  Does that make sense?

redirect_to cannot explicitly return from your method, so you''ll have 
to do it yourself if you want to stop the processing.  e.g.:

def my_action
   if session[:id] == nil
     redirect_to ...
     return
   end
   # .... other stuff
end

(that should be "implicitly" not "explicitly")

What if I took out the if stuff and made it into it''s own method?   
Could the method stop the processing and not return back to the  
controller method?

I think what you are looking for is a Before Filter, check out the
code for the LoginGenerator
(http://wiki.rubyonrails.com/rails/show/LoginGenerator) for examples.
