The meaning of "Retention Expiration" in Location Server Parameters in WCS
In WCS (Wireless Control System) Help i found this description: "Enter a Retention Expiration value in minutes. This determines how long the received information is stored by the client before it is overwritten. The default value is 24 hours (1440 minutes)."
I use SOAP to access the location server and get its location data about the client. Which client is meant in the description? There is no need for a client (for example my application) to save the information; it always gets the newest Information from Location Server with the new request!?
Here the exact link in WCS to this parameter: Mobility-> Mobility Service Engines->SERVER_NAME->Location->Presence Parameters!
Please help me to understand what this parameter is good for!
