A server receives a web-protocol request from a client that triggers a server-side operation in response to the request. Based on a result of the operation, the server identifies first text information to be returned to the client. A language associated with the client device is determined. A determination is made as to whether a resource file corresponding to the determined language is loaded in a volatile memory on the server. In a case where a resource file corresponding to the determined language is not loaded in the volatile memory, the resource file corresponding to the determined language is loaded from a non-volatile memory into the volatile memory on the server. Second text information which corresponds to the first text information to be returned to the client device is retrieved from the resource file in the volatile memory. The second text information is transmitted to the client.
