Hi Alan,

I tried to do that using the cache module. I set

   key = "%{Acct-Session-Id}"

in the module config and then called

   post-auth {
     cache
   }

in inner-tunnel, but that way, Acct-Session-Id expands to an empty string.

Do you happen to have an example somewhere of how to use the cache 
module for such a short-term storage?

Thanks,
Nik
