I have a webservice client, it can handle only 30 records returned from web service at a time. so they will pass in a parameter for the max number of records to return (which should be 30) and then for subsequent calls, they'll just simply pass in a "Next" flag, meaning we should return the next batch of records from our webservice.
so, the web service will need to keep track of all this from one call to the next, and if sessions work it'll make things easier.
Is there a similar concept to sessions when using web services? I.e., is there a way to tell from a subsequent call to a web service whether it's from the same client? Do web service clients have sessions, session IDs, etc. like regular web users?
