Description:
------------
When I try to make HTTP keep-alive connection, script behaves ununderstood.

When I am making two request per one connection, using header "Connection:keep-
alive", script processes only one. Second request, although it was written into 
socket, it returns an empty result, due to the fact that the pointer is EOF.

Test script:
---------------
<?php
/*
file 1.txt on localhost contains text: 1
file 2.txt on localhost contains text: 2
*/
function run($fp, $c, $u) {
	if ($fp) {
		fwrite($fp, "GET {$u} HTTP/1.0\r\nHost: localhost\r\nConnection: {$c}\r\n\r\n");
		$data = '';
		while (!feof($fp)) {
			$data .= fgets($fp);
		}
		return $data;
	}
}

//trying to use keep-alive
$fp = stream_socket_client("tcp://localhost:80", $errno, $errstr, 30);
echo run($fp, "keep-alive", "/1.txt");
echo run($fp, "keep-alive", "/2.txt");
fclose($fp);

//trying to use close
$fp = stream_socket_client("tcp://localhost:80", $errno, $errstr, 30);
echo run($fp, "close", "/1.txt");
fclose($fp);
$fp = stream_socket_client("tcp://localhost:80", $errno, $errstr, 30);
echo run($fp, "close", "/2.txt");
fclose($fp);


Expected result:
