using (HttpWebResponse wresp = (HttpWebRes         


        

Answer 1

This is more efficient for you especially if you need to stream a video from a file on your server or even this file is hosted at another server

File On your server:

context.Response.BinaryWrite(File.ReadAllBytes(HTTPContext.Current.Server.MapPath(_video.Location)));

File on external server:

var wc = new WebClient();
    context.Response.BinaryWrite(wc.DownloadData(new Uri("http://mysite/video.mp4")));

Answer 2

You're reading the entire file into a single buffer, then sending the entire byte array at once.

You should read into a smaller buffer in a while loop.

For example:

byte[] buffer = new byte[4096];

while(true) {
    int bytesRead = myStream.Read(buffer, 0, buffer.Length);
    if (bytesRead == 0) break;
    Response.OutputStream.Write(buffer, 0, bytesRead);
}
