Get multiple pages with a single fsockopen

Question

All. I need to get the contents of several pages from one domain. Now for each page, I use the fsockopen connection, and I get the contents of the page as follows:

<?php
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br />\n";
} else {
    $out = "GET /page1.html HTTP/1.1\r\n";
    $out .= "Host: www.example.com\r\n";
    $out .= "Connection: Close\r\n\r\n";
    fwrite($fp, $out);
    while (!feof($fp)) {
        fgets($fp, 128);
    }
    fclose($fp);
}

My script spends time reconnecting to the domain to get a second page. I was wondering if you can use one connection and get multiple pages, for example:

<?php
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br />\n";
} else {

    $out = "GET /page1.html HTTP/1.1\r\n";
    $out .= "Host: www.example.com\r\n";
    $out .= "Connection: Close\r\n\r\n";
    fwrite($fp, $out);
    while (!feof($fp)) {
        fgets($fp, 128);
    } $out = "GET /page2.html HTTP/1.1\r\n";
    $out .= "Host: www.example.com\r\n";
    $out .= "Connection: Close\r\n\r\n";
    fwrite($fp, $out);
    while (!feof($fp)) {
        fgets($fp, 128);
    }
    fclose($fp);
}

But this method returns page1.html two times, I don’t know why.

I tried using: Connection: keep alive, or HTTP / 1.0, but in this case I didn’t get anything from the server (infinite runtime of my script).

Any suggestion to solve this?

Thank!

Connection: Close .

:

$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br />\n";
} else {

    $out = "GET /page1.html HTTP/1.1\r\n";
    $out .= "Host: www.example.com\r\n";
    // DON'T SEND Connection: Close HERE
    fwrite($fp, $out);
    while (!feof($fp)) {
        fgets($fp, 128);
    } 

    $out = "GET /page2.html HTTP/1.1\r\n";
    $out .= "Host: www.example.com\r\n";
    // THIS IS THE LAST PAGE REQUIRED SO SEND Connection: Close HEADER
    $out .= "Connection: Close\r\n\r\n";
    fwrite($fp, $out);
    while (!feof($fp)) {
        fgets($fp, 128);
    }
    fclose($fp);
}
