PHP fsockopen subfolder - php

Question

I have a page on my website that have a really long execution time, i solved the problem of the fact that it was too slow by flushing contents while writing, but now i need to load it from another website, if i had to do it from my website a include would have been enough, but since i need to load it from another website, i thought of using file_get_contents, the problem is that in this way the flushs don't work, and the page take a lot of time to load, i heard that the solution was using fsockopen and fread, so i tried to use some examples, and i get a thing like this
<?php
ob_start();
$fp = fsockopen("www.mysite.com", 80);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
fwrite($fp, "Data sent by socket");
$content = "";
while (!feof($fp)) {
$content .= fread($fp, 1024);
ob_flush();
}
fclose($fp);
echo $content;
}
?>
The problem is that if i do this it work, but when i try something like
<?php
ob_start();
$fp = fsockopen("www.mysite.com/subfolder/index.php", 80);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
fwrite($fp, "Data sent by socket");
$content = "";
while (!feof($fp)) {
$content .= fread($fp, 1024);
ob_flush();
}
fclose($fp);
echo $content;
}
?>
It says me something like:
Warning: fsockopen(): php_network_getaddresses: getaddrinfo failed: No such host is known. on line 2
What am I mistaking?

UPDATE: Solved by myself: the correct code is
<?php
function HTTP_Post($URL) {
ob_start();
$URL_Info=parse_url($URL);
$fp = fsockopen($URL_Info["host"],80);
fwrite($fp, "GET ".$URL_Info["path"]." HTTP/1.0\r\n" );
fwrite($fp, "Host: ".$URL_Info["host"]."\r\n");
fwrite($fp, "Connection: Close\r\n\r\n");
while(!feof($fp)) {
echo fgets($fp, 1024);
ob_flush();
flush();
}
fclose($fp);
}
ini_set('max_execution_time', 300);
HTTP_Post("http://www.corriere.it/cronache/");
?>
