in thread System and CGI - File Created but not the Content

... write a daemon that runs a normal user, validates it input and executes the program. The CGI script and the daemon can communicate via TCP or named pipes.
How do you do that? Using Perl script? Do you have any example of it?
Sorry I'm quite new to this, so obvious thing may not be obvious to me.

    Here is an example how you write a perl script that moves itself into the background (might not work on windows...):

    !/usr/bin/perl use strict; use warnings; my $ret_val = fork(); if (! defined $ret_val){ die "Can't fork(): $!"; } elsif ($ret_val == 0){ # do your daemon tasks here sleep 5; print "Exiting\n"; } else { exit 0; }

    As for the server you should check the Net::Server module.
