NAME

6       Net::HTTP::NB - Non-blocking HTTP client
7

SYNOPSIS

9        use Net::HTTP::NB;
10        my $s = Net::HTTP::NB->new(Host => "www.perl.com") || die $@;
11        $s->write_request(GET => "/");
12
13        use IO::Select;
14        my $sel = IO::Select->new($s);
15
16        READ_HEADER: {
17           die "Header timeout" unless $sel->can_read(10);
18           my($code, $mess, %h) = $s->read_response_headers;
19           redo READ_HEADER unless $code;
20        }
21
22        while (1) {
23           die "Body timeout" unless $sel->can_read(10);
24           my $buf;
25           my $n = $s->read_entity_body($buf, 1024);
26           last unless $n;
27           print $buf;
28        }

DESCRIPTION

31       Same interface as "Net::HTTP" but it will never try multiple reads when
32       the read_response_headers() or read_entity_body() methods are invoked.
33       This make it possible to multiplex multiple Net::HTTP::NB using select
34       without risk blocking.
35
36       If read_response_headers() did not see enough data to complete the
37       headers an empty list is returned.
38
39       If read_entity_body() did not see new entity data in its read the value
40       -1 is returned.
