		1039	=head2 SOCKS PROXIES
		1040
		1041	Socks proxies are not directly supported by AnyEvent::HTTP. You can
		1042	compile your perl to support socks, or use an external program such as
		1043	F<socksify> (dante) or F<tsocks> to make your program use a socks proxy
		1044	transparently.
		1045
		1046	Alternatively, for AnyEvent::HTTP only, you can use your own
		1047	C<tcp_connect> function that does the proxy handshake - here is an example
		1048	that works with socks4a proxies:
		1049
		1050	use Errno;
		1051	use AnyEvent::Util;
		1052	use AnyEvent::Socket;
		1053	use AnyEvent::Handle;
		1054
		1055	# host, port and username of/for your socks4a proxy
		1056	my $socks_host = "10.0.0.23";
		1057	my $socks_port = 9050;
		1058	my $socks_user = "";
		1059
		1060	sub socks4a_connect {
		1061	my ($host, $port, $connect_cb, $prepare_cb) = @_;
		1062
		1063	my $hdl = new AnyEvent::Handle
		1064	connect => [$socks_host, $socks_port],
		1065	on_prepare => sub { $prepare_cb->($_[0]{fh}) },
		1066	on_error => sub { $connect_cb->() },
		1067	;
		1068
		1069	$hdl->push_write (pack "CCnNZZ", 4, 1, $port, 1, $socks_user, $host);
		1070
		1071	$hdl->push_read (chunk => 8, sub {
		1072	my ($hdl, $chunk) = @_;
		1073	my ($status, $port, $ipn) = unpack "xCna4", $chunk;
		1074
		1075	if ($status == 0x5a) {
		1076	$connect_cb->($hdl->{fh}, (format_address $ipn) . ":$port");
		1077	} else {
		1078	$! = Errno::ENXIO; $connect_cb->();
		1079	}
		1080	});
		1081
		1082	$hdl
		1083	}
		1084
		1085	Use C<socks4a_connect> instead of C<tcp_connect> when doing C<http_request>s,
		1086	possibly after switching off other proxy types:
		1087
		1088	AnyEvent::HTTP::set_proxy undef; # usually you do not want other proxies
		1089
		1090	http_get 'http://www.google.com', tcp_connect => \&socks4a_connect, sub {
		1091	my ($data, $headers) = @_;
		1092	...
