Hi
i have been using the jfileupload for quite sometimes now, and i have came across a problem one of our customer have.
the jfileupload works fine for people with normal broadband, but does not work for those people behind a proxy.

I have configured the jfileupload to work with proxy before, but the actual server was behind the proxy itself.
The problem now has got a different scenario. the server does not use proxy, but users that uses it have probrem.
It does return the following error:
"Attention required (The ISA Server requires authorization to fullfill the request... etc etc etc)".

Could someone advice on this problem ??
thanks

I would need you to enable DEBUG mode and post here the traces. See level 2 mode at:

Dear support
Below is the java error log i have been given from the customer.

Hope that can help raise a possible solution.
This problem is getting close to be a serious issue for the kind of business i have.

thanks

Please update to release 2.4.
Also, add the following parameter because your proxy ask for authentication:
<PARAM NAME="authentication" VALUE="auto">

Does it help ?

I can confirm that that line solved the problem..

thank you for the quick response.

Great !
