Chrome showing "canceled" on successful file download (200 status)

Not sure if this is an actual problem or not, but I'm writing a file out in ASP.NET, and even though the file always successfully goes through, in Chrome's developer tools, network tab, I always see the line in red, marked "Canceled". I've tried lots of ways of doing this - for simplicity, I'm trying this with a simple text file, but it's true for PDF and other file types as well. WebForms: I've tried it with lots of combinations of the following: ``` Response.Clear(); // and/or/neither Response.ClearHeaders(); // with and without this Response.Buffer = true; Response.Charset = ""; // or/neither Response.Charset = "utf-8"; // application/pdf for PDF, also tried application/octet-stream Response.ContentType = "text/plain"; // with and without this Response.AddHeader("Content-Length", bytes.Length.ToString()); Response.AddHeader("Content-Disposition", "attachment; filename=1.txt"); // bytes is the UTF8 bytes for a string or the PDF contents new MemoryStream(bytes).WriteTo(Response.OutputStream); // or Response.Write("12345"); // any combination of the following 3, or none at all Response.Flush(); Response.Close(); Response.End(); ``` MVC (2 and 3, haven't tried 4): ``` byte[] fileContents = Encoding.UTF8.GetBytes("12345"); return File(fileContents, "text/plain", "1.txt"); // or return File(@"C:\temp\1.txt", "text/plain", "1.txt"); ``` It's always the same - the file goes through just fine, but dev tools shows me this: I'm thinking of just ignoring it and moving on with life, but the red just bothers me. Any idea how I can deal with that?
