What does this error mean? The remote host closed the connection. The error code is 0x80070057

Question

Even though a couple people have asked this question it seems there problem is different than mine. Like most of them seem to get line numbers or the problem might be caused with ViewState.

I am using Asp.net 4.0 MVC 2.0 so I don't think I am using ViewState at all. My error does not give me line numbers are well. So I have no clue what is causing it or where in my code.

System.Web.HttpException (0x80070057): The remote host closed the connection. The error code is 0x80070057.

Anyone know why?

Answer 1

We were mixing "Response.Redirect" with "return View()" that caused this issue. The browser was redirected, but we tried to still return a view...

BAD CODE

    switch (userType)
    {
        case "None":
            Response.Redirect("http://" + host + "/");
            break;
        default:
            Response.Redirect(internalwebhost + "/exit/");
            break;
    }

    return View();

BETTER CODE

    switch (userType)
    {
        case "None":
            url = "http://" + host + "/";
            break;
        default:
            url = internalwebhost + "/exit/";
            break;
    }

    return new RedirectResult(url);

Answer 2

Server couldn't send the answer to the client. Network connection lost on the client could be a cause.

Not sure if closing the browser/tab at the very precise time would also give the error.
