Problem with .tmp file in AsyncUpload

[Tri Nguyen]

Hello,

I am using version 2017.3.913.40. The code segment to save a file, using the AsyncUpload control, works only the first time. If I upload a different file, I would the get an error message, see attachment, that it tried to look for a file with extension .tmp. I put the following lines in the Web.config, based on a suggestion on a thread I found. But it doesn't seem to fix the problem. Could you help?

<add key="Telerik.AsyncUpload.TemporaryFolder" value="~/RadUploadTemp" />
<location path="RadUploadTemp">
    <system.web>
      <authorization>
        <deny users="*" />
      </authorization>
    </system.web>
  </location>
