  sessionTable 
    The name of the database table to be used for storing swapped out sessions.
      This table must contain, at least, the database columns
      that are configured by the other attributes of this element.

  Name 
    Value 
  
     
  timeoutSeconds 
    The default maximum inactive interval, in seconds, for all sessions created in this web module.
      If set to 0 or less, sessions, this web module never expire. 
  
     
  enableCookies 
    If this property is set to true, cookies are used for session tracking. 
  
     
  enableURLRewriting 
    If this property is set to true, URL rewriting is enabled.
