I don't know with Apache::ASP, but it can probably be done. With
HTMl::Embperl it would be pretty trivial.
You could probably get quite a gain with having a squid or a
mod_proxy process in front. Both because they would slurp up the
data and feed it to slow clients and because if you could cache the
documents for just a minute or so it might save quite some hits on
the backend.

Have a look at ftp://ftp.netcetera.dk/pub/apache/mod_proxy_add_forward.c
