NAME
       Net::HTTP::NB - Non-blocking HTTP client

SYNOPSIS
        use Net::HTTP::NB;
        my $s = Net::HTTP::NB->new(Host => "www.perl.com") || die $@;
        $s->writerequest(GET => "/");

        use IO::Select;
        my $sel = IO::Select->new($s);

        READHEADER: {
           die "Header timeout" unless $sel->canread(10);
           my($code, $mess, %h) = $s->readresponseheaders;
           redo READHEADER unless $code;
        }

        while (1) {
           die "Body timeout" unless $sel->canread(10);
           my $buf;
           my $n = $s->readentitybody($buf, 1024);
           last unless $n;
           print $buf;
        }

DESCRIPTION
       Same interface as "Net::HTTP" but it will never try multiple reads when
       the readresponseheaders() or readentitybody() methods are invoked.
       This make it possible to multiplex multiple Net::HTTP::NB using select
       without risk blocking.

       If readresponseheaders() did not see enough data to complete the
       headers an empty list is returned.

       If readentitybody() did not see new entity data in its read the value
       -1 is returned.
