Implementation of wp session manager

Hi,

I want to implement wp session manager to my web side.
I waqnt to write and read $wp_session[‘user_contact’] = array( ’email’ => ‘[email protected]’ ); with a java script code on a side.
Has anybody an idea or an example how I could realize it?

For a solution I would owe some beers, when ever you are visiting cologne (Germany)

Muchas gratias

Christian
