help using Inets and ESP

[Erlang Question]

 Hi!
 I have a interesting question....
 I´m developing a web interface in esp to access mnesia running under inets,
 and I would like to have control of the user logged in the system. So I
 need to define session variable to manage the active user in the system.

  So here is my question:
 Anybody knows if Inets supports session variables? (like apache)
 If support, then how i define one?
 if not, anybody know a trick or tip to simulate a session variable looking
 my case? I suppose that someone must need it sometime? any kind of help
 it'll be great!

 thanks in advance...gabriel!
