Saving a stream in TempData MVC5 C# - asp.net-mvc-5

Question

Hi i am uploading a large file using asp.net mvc5 to server and in controler i am saving this stream into TempData.on my local machine it is working fine and successfully uploading large files.but on hosted server it fails.i have tried it with increasing MaxAllowedContent and ExcutionTimeOut Limit but none of them worked.Can anyone help me on this.
Here is my controller action
public ActionResult UploadTransactionPDF()
{
private readonly List<MemoryStream> _PdfImage = new List<MemoryStream>();
private readonly List<string> _PdfImageNames = new List<string>();
try
{
Gateway.Instance.Logger.LogInfo(string.Format(_formatProvider,"[TransactionController -> UploadTransactionPDF ]: method started : Save pdf to memory."));
if (CheckFileExist())
{
if (TempData[TransactionRef.PdfFiles.ToString()] != null)
{
_PdfImage.Clear();
_PdfImage.AddRange(TempData[TransactionRef.PdfFiles.ToString()] as List<MemoryStream>);
}
if (TempData[TransactionRef.PdfFileName.ToString()] != null && !string.IsNullOrEmpty(TempData[TransactionRef.PdfFileName.ToString()].ToString()))
{
_PdfImageNames.Clear();
_PdfImageNames.AddRange(TempData[TransactionRef.PdfFileName.ToString()] as List<string>);
}
for (int a = 0; a < Request.Files.Count; a++)
{
if (!_PdfImageNames.Contains(Request.Files[a].FileName))
{
MemoryStream ms = new MemoryStream();
Request.Files[a].InputStream.CopyTo(ms);
_PdfImage.Add(ms);
_PdfImageNames.Add(Request.Files[a].FileName);
}
}
TempData[TransactionRef.PdfFiles.ToString()] = _PdfImage;
TempData[TransactionRef.PdfFileName.ToString()] = _PdfImageNames;
ViewBag.Info = "pdf";
ViewBag.ImageUploadInfo = Language.ImageSavedMessage.ToString();
}
else
{
ViewBag.ImageUploadInfo = Language.NoFileMessage.ToString();
}
ViewBag.FileNames = _PdfImageNames;
Gateway.Instance.Logger.LogInfo(string.Format(_formatProvider, "[TransactionController -> UploadTransactionPDF ] : method exited ."));
return View("_PDFFiles");
}
catch (Exception ex)
{
string errorInfo = string.Format(_formatProvider, "[TransactionController -> UploadTransactionPDF ] : Error : '{0}' occurred while saving pdf to memory.",ex.Message);
Gateway.Instance.Logger.LogError(errorInfo,ex);
throw new Exception(errorInfo, ex);
}
}
Thanks!

can you see if the following exists in your web.config on the dev enviroment versus on the server. ddddd should be the max your request should allow. don't make it to high to where you open yourself up for DOS. the request length wouldn't just be the file size but the entire request from the client to the server.
<configuration>
<system.web>
<httpRuntime targetFramework="4.5" maxRequestLength="ddddd" />
</system.web>
</configuration>
you can localize it to the one controller action by adding a location element in between the configuration and system.web elements.
