If you're running your scripts in Apache2::Registry, your scripts are
compiled on first go, and remain in memory subsequently.
When your script changes, the change should be detected, and
recompilation is automatic. IMHO this is a real time saver as
development goes.
do() is bad for speed optimisation as it's treated as a system call.
What you want instead is to modify your header.pl into a package, and
have your scripts call functions in the package. Minimise exec() calls
as well (ideally you should not use it at all).

Hello -
Am executing several CGI scripts under mod_perl using Apache::Registry (I hope
that terminology is correct). As I understand it, the scripts get cached in
each httpd thread the first time that thread executes them. Is this correct?
So when I change a script, do I need to restart Apache, flush the cache
somehow, or does each thread automagically replace the cached copy with the
updated one from disk?
Basic stuff, but I'm curious...
The main focus of my writing today is to get some guidance on the proper direction to
take for this project. Currently, each of the CGI scripts I have "sources" the
same set of files (one for the header, another for the footer, etc). Per the above
questions, I don't how the mod_perl processes work to keep everything in sync but I can
only imagine that having each of my CGI scripts source the same files from disk has to be
grossly inefficient.
Am thinking that all these external scripts should be packaged up together into mod_perl
somehow, but I don't know where I should be looking. Can someone shed some light? In
doing so, one possible constraint is that I'm also executing the same external scripts
from several SHTML files. The CGI scripts call the filesystem based subroutines after
initially sourcing them with 'do ./header.pl' whereas the SHTML files pass in a
"go" argument to 'header.pl' to actually fire up the subroutine. This allows
me to execute them immediately using SHTML 'exec' calls and 'on demand' from the CGI
scripts.
Thanks in advance for your guidance / direction.
