Abstract
Methods for synchronizing data in client-server architectures are described. A client stores data in first and second fields. The value stored in the second field depends on the value stored in the first. When the client writes a new value to the first field, it disables writing to the second field. The client sends a refresh request and receives a refresh response from a server. The refresh request and response contain differences in data stored in the client and server fields. If the refresh response includes a new value for the second field, the client writes the value to the second field. A round trip pending flag associated with the first field is set. A data invalid flag associated with the second field is set. New data can be written to a third field when the value of the third field does not depend on the value of the first field.
