Description:

I've been looking for some way of making HTTP::Daemon work over SSL. I could find this thread very useful, but most of the given solutions implied patching Daemon.pm, stopping it from serving as a regular http daemon.

The trick here is simply to dynamically change the inheritance of HTTP::Daemon to make it an heir of IO::Socket::SSL instead of IO::Socket::INET

use HTTP::Daemon;
use IO::Socket::SSL;

@HTTP::Daemon::ISA = qw/ IO::Socket::SSL /;
@HTTP::Daemon::ClientConn::ISA = qw/ IO::Socket::SSL /;

my $server = new HTTP::Daemon
    SSL_cert_file => 'cert.pem',
    SSL_key_file => 'key.pm',
    LocalPort => 443,
    ReuseAddr => 1,
;

while ( my $client = $server->accept() ) {
    ...
    $client->close(SSL_no_shutdown => 1);
}

$server->close(SSL_no_shutdown => 1);
