It's better not to put this stuff into mod_perl because you'll have issues with memory
etc. And the time you gain is nothing to compare with the time needed
to start external process.
Put it in regular CGI script. And to catch output from external program
use standart methods like backticks, pipe, etc. If you need to provide some
input to that external program then you may want to use the following method.
$pid = open(IN, "-|");
if($pid == 0){ #child, STDOUT -> parent
open(OUT, "|external_program");
print OUT @stuff_for_external_program;
close(OUT); # wait for it to finish;
exit 0;
}
@from_external_program = <IN>;
Add child reaper and you should be all set.
