Subject Re: Why WebApp programming is harder than necessary with C2

+1 for redirects from actions but, from the SoC point of view, if the sitemap
is the only tool to manage URI space of the webapp, and you do direct redirect
from action you break this, e.g, allowing redirect from action you can break
the application from working because sitemap admin will not work with action's
source code.

the other way around, you have to be able to control redirects via runtime
parameters given to actions upon invocation and it is IMO the same as doing
sitemap-only redirects, 

we have to more think about previously proposed flowmap, I'll throw out RT
that I prepared for my final project soon...
