Hi Terry

 

Some more information for you:

I am using the upload tool in a ModalPopupExtender control - the Microsoft Ajax control.  This seems to cause two different problems...

1) When behind HTTPS it stops at a random percentage right towards the end of the upload and does nothing.  I can confirm that even though I am setting the temp directory correctly it isn't showing any temp file in there during the upload process so I am not sure where it is being uploaded to?

2) When not behind HTTPS it gives me the error: 'The upload task is interrupted! IO' and I can then see the uploaded file in a list with an exclamation mark next to it.

 

If I don't put the control inside the ModalPopupExtender control then it seems to work fine.

 

Any ideas?

 

Kind regards

 

Andrew
