Net::HTTP::NB - Non-blocking HTTP client
use Net::HTTP::NB;
my $s = Net::HTTP::NB->new(Host => "www.perl.com) || die $@;
$s->write_request(GET => "/");
use IO::Select;
my $sel = IO::Select->new($s);
READ_HEADER: {
die "Header timeout" unless $sel->can_read(10);
my($code, $mess, %h) = $s->read_response_headers;
redo READ_HEADER unless $code;
}
while (1) {

}
Same interface as Net::HTTP but it will never try multiple reads
when the read_response_headers() or read_entity_body() methods are
invoked. This make it possible to multiplex multiple Net::HTTP::NB
using select without risk blocking.
If read_response_headers() did not see enough data to complete the
headers an empty list is returned.
If read_entity_body() did not see new entity data in its read
the value -1 is returned.
