Instead of using a webserver, have your Perl script fork off its own server (if one isn't running at the time). It can communicate on a socket. We have a CGI program that keeps an large XSLT in standby. Using IO::Socket:
my $sock = new IO::Socket::INET ( LocalHost => $server,
LocalPort => 9200,
Proto => 'tcp',
Listen => 2,
ReuseAddr => 1,
);
die "socket creation error: $!" unless $sock;
while( my $client = $sock->accept() ) {
binmode $client, ":utf8";
$client->autoflush(1);
# Read data
while( $client->recv( $in_buffer, $buffer_size ) ) {
# Store data
}
# Process data
# Return data
$client->send( $output );
}
Some things to consider to make it dummy proof is allow it to adjust what port is runs on at runtime, and to have the server exit after a while to avoid zombie processes. |
