Caching object in the Application or Session Object?

[solex]

For some reason I cannot seem to get a response for this question on any
of the appropriate microsoft news groups:

What is the consensus with caching immutable data? I would like to
implement a load on demand identity map (using visual basic) in the
application.contents or session object.

Basically if client requests an object the application would first check
the identity map if it is not found then load it from the database and
then insert into the map for future reference then return the object.

Thanks,

Dan
