I have tried searching on here and Google for an answer to this but have yet to find one. I am using what I have found to be fairly standard for .NET 4.0 upload to Web API service. Here is the code:<\/p>\n
public HttpResponseMessage Post()\n {\n if (!Request.Content.IsMimeMultipartContent())\n {\n throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);\n }\n StringBuilder sb = new StringBuilder();\n\n string root = HttpContext.Current.Server.MapPath(\"~\/App_Data\");\n var provider = new MyMultipartFormDataStreamProvider(root);\n\n var task = Request.Content.ReadAsMultipartAsync(provider).ContinueWith(t =>\n {\n if (t.IsFaulted || t.IsCanceled)\n {\n Request.CreateErrorResponse(HttpStatusCode.InternalServerError, t.Exception);\n }\n\n \/\/ This will give me the form field data\n foreach (var key in provider.FormData.AllKeys)\n {\n foreach (var val in provider.FormData.GetValues(key))\n {\n sb.Append(string.Format(\"{0}: {1}\", key, val));\n }\n }\n\n \/\/ This will give me any file upload data\n foreach (MultipartFileData file in provider.FileData)\n {\n sb.Append(file.Headers.ContentDisposition.FileName);\n sb.Append(\"Server file path: \" + file.LocalFileName);\n }\n return new HttpResponseMessage()\n {\n Content = new StringContent(sb.ToString())\n };\n });\n return Request.CreateResponse(HttpStatusCode.OK);\n }\n<\/code><\/pre>\nWhen I create a very basic form with a input type=file and submit it I am getting an exception thrown for files over about 800Kb. Here is the exception:<\/p>\n

This small part is not always the same size either, like maybe it cuts off at a certain size.<\/p>\n
I have adjusted both the maxRequestLength<\/code> and the maxAllowedContentLength<\/code> to large numbers with no success.<\/p>\nWhat does this message mean and what should I be looking at to fix it?<\/p>\n
Thanks.<\/p>\n
