NAME

       Net::HTTPS::NB - Non-blocking HTTPS client

SYNOPSIS

       Example from Net::HTTP::NB
		   use Net::HTTPS::NB;
		   use IO::Select;
		   use strict;

		   my $s = Net::HTTPS::NB->new(Host => "pause.perl.org") || die $@;
		   $s->write_request(GET => "/");

		   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;
		   }

       Example of non-blocking connect
		   use strict;
		   use Net::HTTPS::NB;
		   use IO::Select;

		   my $sock = Net::HTTPS::NB->new(Host => 'encrypted.google.com', Blocking => 0);
		   my $sele = IO::Select->new($sock);

		   until ($sock->connected) {
			   if ($HTTPS_ERROR == HTTPS_WANT_READ) {
				   $sele->can_read();
			   }
			   elsif($HTTPS_ERROR == HTTPS_WANT_WRITE) {
				   $sele->can_write();
			   }
			   else {
				   die 'Unknown error: ', $HTTPS_ERROR;
			   }
		   }

DESCRIPTION

       Same interface as Net::HTTPS but it will never try multiple reads when the read_response_headers() or read_entity_body() methods are
       invoked. In addition allows non-blocking connect.

       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.

PACKAGE VARIABLES

	       $HTTPS_ERROR

METHODS

   new(%cfg)
       Same as Net::HTTPS::new, but in addition allows `Blocking' parameter. By setting this parameter to 0 you can perform non-blocking connect.
       See connected() to determine when connection completed.

   connected()
       Returns true value when connection completed (https handshake done). Otherwise returns false. In this case you can check $HTTPS_ERROR to
       determine what handshake need for, read or write. $HTTPS_ERROR could be HTTPS_NEED_READ or HTTPS_NEED_WRITE respectively. See "SYNOPSIS".

   blocking($flag)
       As opposed to Net::HTTPS where blocking method consciously broken you can set socket blocking. For example you can return socket to
       blocking state after non-blocking connect.
