Auth MemCache Cookie

Hello,

This mod is great, it would perfectly fit the needs of my project.
But i am missing one thing ; let's make it simple :

A page of my site is accessible by everybody (the page is not filtered by mod_Authmemcookie).
But if the user is logged in, he should have access to some more private data, on that same page.

To do so, i need to access the session info of the logged user, in that unprotected page. But it seems that those info are set into the request only if the page is protected.
--> Am i right so far ?
--> Is there a way to force those session info into that unprotected page request ?

(My test consists in seeing my session info through phpinfo().)

Your help woul be greatly appreciated ! :-)

Cheers
EDumas
