PHP Website not responding while streaming a video

My website is developed using pure PHP with MySQL while streaming a video "Please try this link" Here

If you click on any button called "مشاهدة", the website will not respond to any other request like navigating to any other page.

Here is the code of my Stream.php file

<?php

session_start();
require("includes/connect.php");

set_time_limit(0);
if(isset($_GET["file"])){
    if(!isset($_GET["start"])) $_GET["start"] = 0;
    $seekPos = $_GET["start"];
    $file = htmlspecialchars($_GET["file"]);
    $fileName = basename($file);
    $file = $config["videoFilesPath"]."/".$fileName;
    if(!file_exists($file)) die("file does not exist: $file");
    $fh = fopen($file, "rb") or die("failed to open file");
    fseek($fh, 0, SEEK_END); $seek_end = ftell($fh);
    fseek($fh, $seekPos); $seek_start = ftell($fh);
    $fileSize =  $seek_end - $seek_start;
    session_cache_limiter('nocache');
    header("Expires: Thu, 19 Nov 1981 08:52:00 GMT");
    header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
    header("Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0");
    header("Pragma: no-cache");
    header("Content-Type: video/x-flv");
    //header("Content-Disposition: attachment; filename=\"" . $fileName . "\"");
    header('Content-Length: ' . $fileSize);
    if($seekPos != 0){
        print("FLV");
        print(pack('C', 1 ));
        print(pack('C', 1 ));
        print(pack('N', 9 ));
        print(pack('N', 9 ));
    }
    fseek($fh, $seekPos);
    $i=1;
    while (true){
        $var = fread($fh, 1024);
        if($var==false) break;
        echo $var;
        if(++$i%(1<<20)) ob_flush();
    }
    fclose($fh);
}

session_start() opens and locks the session file, therefore you must call session_write_close() before any long running process:

session_start();
require("includes/connect.php");
session_write_close();
