All pages listener/interceptor

[albartell]

I am looking for a slick way to implement a global "phase listener" that
will be used to check whether or not a user is logged in before letting them
proceed to a page on the site.  Here is an example of how I did it in JSF:

I have yet to find a global way in Tapestry...I know I could use a
PageBeginRenderListener but then I would have to put that code into each
page (yes I am a lazy programmer :-)
 
Thanks in advance,
