/**
 * Cookie management policy class. The cookie policy provides corresponding

 * 

RFC 2109 specification is used per default. Other supported specification * can be chosen when appropriate or set default when desired *

The following specifications are provided: *

    *
  • COMPATIBILITY: compatible with the common cookie management * practices * (even if they are not 100% standards compliant) *
  • NETSCAPE_DRAFT: Netscape cookie draft compliant *
  • RFC2109: RFC2109 compliant (default) *
*
