		1024	=head2 SOCKS PROXIES
		1025
		1026	Socks proxies are not directly supported by AnyEvent::HTTP. You can
		1027	compile your perl to support socks, or use an external program such as
		1028	F<socksify> (dante) or F<tsocks> to make your program use a socks proxy
		1029	transparently.
		1030
		1031	Alternatively, for AnyEvent::HTTP only, you can use your own
		1032	C<tcp_connect> function that does the proxy handshake - here is an example
		1033	that works with socks4a proxies:
		1034
		1035	use Errno;
		1036	use AnyEvent::Util;
		1037	use AnyEvent::Socket;
		1038	use AnyEvent::Handle;
		1039
		1040	# host, port and username of/for your socks4a proxy
		1041	my $socks_host = "10.0.0.23";
		1042	my $socks_port = 9050;
		1043	my $socks_user = "";
		1044
		1045	sub socks4a_connect {
		1046	my ($host, $port, $connect_cb, $prepare_cb) = @_;
		1047
		1048	my $hdl = new AnyEvent::Handle
		1049	connect => [$socks_host, $socks_port],
		1050	on_prepare => sub { $prepare_cb->($_[0]{fh}) },
		1051	on_error => sub { $connect_cb->() },
		1052	;
		1053
		1054	$hdl->push_write (pack "CCnNZZ", 4, 1, $port, 1, $socks_user, $host);
		1055
		1056	$hdl->push_read (chunk => 8, sub {
		1057	my ($hdl, $chunk) = @_;
		1058	my ($status, $port, $ipn) = unpack "xCna4", $chunk;
		1059
		1060	if ($status == 0x5a) {
		1061	$connect_cb->($hdl->{fh}, (format_address $ipn) . ":$port");
		1062	} else {
		1063	$! = Errno::ENXIO; $connect_cb->();
		1064	}
		1065	});
		1066
		1067	$hdl
		1068	}
		1069
		1070	Use C<socks4a_connect> instead of C<tcp_connect> when doing C<http_request>s,
		1071	possibly after switching off other proxy types:
		1072
		1073	AnyEvent::HTTP::set_proxy undef; # usually you do not want other proxies
		1074
		1075	http_get 'http://www.google.com', tcp_connect => \&socks4a_connect, sub {
		1076	my ($data, $headers) = @_;
		1077	...
