Using a server in a distributed computer network to provide an application and supplemental script content to a client in the client's preferred language. A client accesses an application on a server and provides a preferred language for the application. Language pack software modules on the server take the content of the application and convert it into the language desired by the client. The translated application is then sent by the server to the client. A component of the language pack software module is also downloaded from the server to the client for converting supplemental content. A browser residing on the client will retrieve supplemental content from the application on the server. After the language pack component converts the supplemental content, a client script renders it to enhance the application. This approach eliminates the need to create separate applications with separate script content for each language and allows the client to change languages instantaneously.
