Subject Re: Executing code before each action

Go read up on filters.  Here's the short of it:
    - transparent to client and application
    - can modify request / response

Since you can grab the session from the request, you could check for the 
presence of your attribute in the session, set it if it's not there, and 
just breeze past if it is.

and then perform the steps I need in the filter.  Does it then pass the request onto the Action
as per normal?  I assume it does.
