What's the best practice for transferring huge binary files with ASP.NET?

Consider an ASP.NET page with this code:

while (read)
{
   Response.OutputStream.Write(buffer, 0, buffer.Length);
   Response.Flush();
}

The application should be highly performance-tuned and handle thousands on concurrent requests and the main purpose is transferring huge binary file to clients over high speed connecti开发者_如何学JAVAons. I can do the job with an ASP.NET page, with HTTP Handler, IHttpAsyncHandler, ISAPI filter and ...

The question is what is the best choice for this purpose ?

If the page is liable to be I/O bound then I'd go the Async road. But you should use the asynchronous read methods (if available) on your Stream object as well.

To address your comment that you receive this data via a socket, you'll also find that most of the System.Net.Sockets namespace classes support asynchronous behaviour.
