What I meant was that in this case it's 2.Application State which tells a
service in what form that table's data need to be returned, or may be
whether this request for data should be refused because that customer has
read it to many times. This application state might include, for ex, URI
identifying the table, a counter of how many times a specific customer has
read this table, etc.


Thanks
