The short and sweet of it is that you can't. Apache doesn't cache the
output before sending it like some web servers (Roxen comes to mind), it
sends it as you "print" so you can't. There are things you can do.. for
example if your modules are all mod_perl modules you can use the
techniques used by the Filter/Chain modules, or what AxKit does is
overload Apache.pm's print() method and catches the output that way.
Hope that helps...
