Hi Amit,

I have created an ASP .net web application and incorporated necessary changes as suggested in the above post for both Caching and Session Management.
Caching works fine. Coming to Session management, it is working fine when try to create a cache and retrieve in my local. But when i try to retrieve the same session from different machine, unable to get the session value (null exception). According to my knowledge, AppFabric Session management is Outproc. If so why am i not able to get the same session value from different machine? Please help me out.
