I am trying to use the document viewer control in my website. The control works fine on a single server but fails when i tried with 2 load balanced webservers "session has expired, the page will be refreshed in 10 seconds" message and keeps refreshing a few times till it eventually fails with "Invalid XPZ file: Zip end header data is wrong size!" error message.
Server details -
Windows Server 2012 with iis8.1
Asp.Net 4.6.2 in SessionStateMode SQLServer
Can you please let me know what needs to be done to get the control working.
