WebRequest can't retrieve video info?

WebRequest request = WebRequest.Create(new Uri("http://istr03.izlesene.com/data/videos/7213/7213704-360_2-103k.mp4/e5ae7a74a30f645c6fc0c5aa0fde9076/531B29B7"));
request.Method = "HEAD";
using (WebResponse response = request.GetResponse()) {
    double boyut = response.ContentLength / 1024 / 1024;
    string tip = response.ContentType;
}

This code is working for other sites but for this url, an exception is raised; (500) internal server error.

What could be different that the code fails for this url?

I did use fiddler to see what is going on. the url you provided redirected to another URL . 

HEAD http://istr03.izlesene.com/data/videos/7213/7213704-360_2-103k.mp4/e5ae7a74a30f645c6fc0c5aa0fde9076/531B29B7 HTTP/1.1
User-Agent: Fiddler
Host: istr03.izlesene.com

HTTP/1.1 302 Moved Temporarily
Via: 1.1 81.212.99.207 (McAfee Web Gateway 7.3.2.3.0.16052)
Date: Fri, 07 Mar 2014 14:45:20 GMT
Server: nginx/1.4.4
Location: http://sstr06.izlesene.com/data/videos/7213/7213704-360_2-103k.mp4?token=WCk3CCIxJYVC0ESMOs1cFw&ts=1394210720
Connection: Keep-Alive
Content-Type: text/html
Content-Length: 160

So you need to parse Location from first response and do another request to server with HEAD method and you will get content length of video.

HEAD http://sstr06.izlesene.com/data/videos/7213/7213704-360_2-103k.mp4?token=WCk3CCIxJYVC0ESMOs1cFw&ts=1394210720 HTTP/1.1
User-Agent: Fiddler
Host: sstr06.izlesene.com

HTTP/1.1 200 OK

You need to set an User-Agent http header. This specific server expects that probably to sniff the capabilities of the client.

Adapt your code to get the HttpWebRequest and set the UserAgent property:

        var request = (HttpWebRequest) WebRequest.Create(
             new Uri("http://your url here"));
        request.Method = "HEAD";
        request.UserAgent = "spider/1.0"; 

        using (WebResponse response = request.GetResponse())
        {
            double boyut = response.ContentLength / 1024 / 1024;
            string tip = response.ContentType;
        }

The content-length of your url is: 13381446
and the content-type is: video/mp4
