[Erlyaws-list] yaws by-passes appmod after cashing

Well it is a bit of a strange way to handle requests. If you have a root
appmod, why not just handle everything in the appmod? If it helps, my appmod
out script looks like this:

% all static files are in static directory
out(#arg{appmoddata = "static/" ++ _} = A) ->
    {page, [$/|A#arg.appmoddata]};
% scripts do something, but don't produce an output (always a redirect to an
appmod page)
out(#arg{appmoddata = "script/" ++ Rem} = A) ->
    my_scripts:out(Rem, A);
out(#arg{appmoddata = "profile"} = A) ->
out(#arg{appmoddata = "register"} = A) ->

Registration for instance, POST is always to /script/register, which tries
to perform a registration, if successful it redirects to the next page, if
unsuccessful it redirects to /register (setting an error cookie) to display
the registration form again.
