 From the Apache::Session docs:

"Note that Apache::Session does only a shallow check to see if anything 
has changed. If nothing changes in the top level tied hash, the data 
will not be updated in the backing store. You are encouraged to 
timestamp the session hash so that it is sure to be updated."

So in your loop you are updating the nested structure under 'config' but 
nothing at the top level of the hash. To have it stored you would have 
to update a key or value of $session.

HTH,
