You can’t get the cookie data in your JS. The API won’t allow you. What do I have to do to save the cookie in my front end app? Just set the Set-Cookie header in the response from the server side code. The browser should save it automatically. As a developer, you may be able … Read more
I had the same problem and the only solution that worked was: Response.Clear(); Response.ContentType = “Application/msword”; Response.AddHeader(“Content-Disposition”, “attachment; filename=myfile.docx”); Response.BinaryWrite(myMemoryStream.ToArray()); // myMemoryStream.WriteTo(Response.OutputStream); //works too Response.Flush(); Response.Close(); Response.End();
