# 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->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) {
        die "Body timeout" unless $sel->can_read(10);
        my $buf;
        my $n = $s->read_entity_body($buf, 1024);
        last unless $n;
        print $buf;
     }

# DESCRIPTION

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.
