Download request refers to an invalid range.

Not A Problem
When I download a document from my development machine it works fine. But when I download a document after deploying the application in server it gives me "Session expired" error. And when I check the stack trace it says "Download request refers to an invalid range."
I am using DocumentUltimate 4.1

When using DocumentUltimate on Azure (or on other Cloud service or in multi-server environments), you need to make sure:

  1. Sessions are shared between instances.
  2. Document cache folder is shared between instances.
Please read the instructions here:
