File upload unstable

A radupload control is used in our web application. It is working fine in the testing environment. When it is used on our live site, it is working fine most of the time. Once in a while, without showing any error message, the file is not uploaded onto the server, but the file name is written into the table. We couldn't find a pattern to duplicate this error.

Any suggestion to resolve this issue will be really appreciated.

Thanks,

Hi Jason M,

Can you paste here the code you are using to save the file? Is there any server-side exception logged when this problem occurs? I think there might be two things happening:

• Uploading empty files
• Invalid HTTP POST requests made by some malicious bot or user

You can try adding a check if the ContentLength property of the uploaded file is greater than zero. This would filter out empty files.
