org.apache.cocoon.webapps.session.components.SessionManager
This is the basic session component. The main purpose of this component is session handling, maintaining contexts and providing system management functions. The session information is divided into session contexts. Transaction management

Transactions are a series of get/set calls to a sessuib context which must be seen as atomic (single modification). We distingish between reading and writing. Usually parallel reading is allowed but if one thread wants to write, no other can read or write. @author Carsten Ziegeler @version CVS $Id: SessionManager.java,v 1.1 2003/03/09 00:06:08 pier Exp $
