One can reproduce the error with the code below:
public ActionResult ClosingTheConnectionAction(){
try
{
//we need to set buffer to false to
//make sure data is written in chunks
Response.Buffer = false;
var someText = "Some text here to make things happen ;-)";
var content = GetBytes( someText );
for(var i=0; i < 100; i++)
{
Response.OutputStream.Write(content, 0, content.Length);
}
return View();
}
catch(HttpException hex)
{
if (hex.Message.StartsWith("The remote host closed the connection. The error code is 0x800704CD."))
{
//react on remote host closed the connection exception.
var msg = hex.Message;
}
}
catch(Exception somethingElseHappened)
{
//handle it with some other code
}
return View();
}
Now run the website in debug mode. Put a breakpoint in the loop that writes to the output stream. Go to that action method and after the first iteration passed close the tab of the browser. Hit F10 to continue the loop. After it hit the next iteration you will see the exception. Enjoy your exception :-)
