I'm not sure why in this case as your code below
looks fine. I would advise though that you move
your subroutine into a perl module or your
global.asa, as subroutines in ASP scripts can
be tricky because an ASP script itself is compiled
as a subroutine, and variable scoping problems
can result. See my closure problems in the
modperl guide http://perl.apache.org/guide
which Apache::ASP shares with Apache::Registry.

BTW, this use of the include mechanism was never
intended to work by me, and am well impressed that you
came up with another use! Beautiful. More below.

You only need to require global.asa if you are
not running as an ASP script, as Apache::ASP
effectively does this for you.
BTW, it looks like you are setting up a benchmarking
testbed on your server. I would be interested
in how you find FastCGI to perform against
Apache::ASP. If you are up for running the hello world
tests, you can add some data to what we have at
http://www.chamas.com/bench/
Note one of the advantages of Apache::ASP is its
rich object API, which incurs some overhead setting
up, so there is an ease of development vs. performance
trade-off here. You will find for example that
Apache::Registry scripts run CGIs faster than
Apache::ASP will because of this overhead. If you
just want CGI emulation, I would stick with Registry.
