NAME

VERSION

SYNOPSIS

12        use Net::HTTP::NB;
13        my $s = Net::HTTP::NB->new(Host => "www.perl.com") || die $@;
14        $s->write_request(GET => "/");
15
16        use IO::Select;
17        my $sel = IO::Select->new($s);
18
19        READ_HEADER: {
20           die "Header timeout" unless $sel->can_read(10);
21           my($code, $mess, %h) = $s->read_response_headers;
22           redo READ_HEADER unless $code;
23        }
24
25        while (1) {
26           die "Body timeout" unless $sel->can_read(10);
27           my $buf;
28           my $n = $s->read_entity_body($buf, 1024);
29           last unless $n;
30           print $buf;
31        }
32

DESCRIPTION

34       Same interface as "Net::HTTP" but it will never try multiple reads when
35       the read_response_headers() or read_entity_body() methods are invoked.
36       This make it possible to multiplex multiple Net::HTTP::NB using select
37       without risk blocking.
38
39       If read_response_headers() did not see enough data to complete the
40       headers an empty list is returned.
41
42       If read_entity_body() did not see new entity data in its read the value
43       -1 is returned.
