A data relay and information processing method including storing in a
database section identification information for identifying
language-dependent data and replacement data corresponding to the
language-dependent data in association with each other, receiving server
data from the server system, detecting the replacement data from the
database section on the basis of the identification information contained
in the server data, replacing the language-dependent data as contained in
the server data by the replacement data, and transmitting the server data
as replaced to a client system. Thus, even in the case where the language
used in the server system providing a service on the Internet is
different from the language used in the client system, it is possible to
recognize the information from the server by the client with reference to
the replacement data.
