Norton Firewall causes '0 bytes download' problem

I have a web page that allows a user to download data by clicking on a link
button. I then use Aspose.Excel (v1.0.3705) to generate the file for download and then
I call the “Save” method on the Aspose.Excel object to send it to the
Response object. One of our users has Norton Firewall installed and when he
tries to download a large amount of data he gets a message "“0 bytes
downloaded”. It works OK with smaller files. When he disables the Norton
then both large and small files download OK. Has anyone had any experience
with this problem?

We have not met this problem before. Since it works OK when disabling Norton, I guess if there are some setting to disable large file transfer in your clients’ machine.
