/**
    This class keeps the authentication information of a connection 
    persistent until the connection is destroyed. 

    The HTTPConnection object creates a AuthenticationInfo object on a new 
    socket connection and includes this object reference in the HTTPMessage 
    that gets passed to the Delegator and in turn to the AuthenticationManager.
    The AuthenticationManager and the related authentication classes use the 
    AuthenticationInfo to store and access the persistent authentication 
    information for a connection.
