Re: [perl #88080] Listen to socket does not return when host isundefined or 0.0.0.0.

Hej!

I have run:

    use strict;
    use warnings;

    use HTTP::Server::Simple;

    my $server = HTTP::Server::Simple->new();
    $server->host( undef );
    #$server->host( '0.0.0.0' );
    $server->run();

Using "$server->host( undef );" or "$server->host( '0.0.0.0' );" works 
with HTTP::Server::Simple version 0.51!

Best regards
Bo Johansson
