In response thereto, the RM server identifies the type of data being requested, i.e. text, audio, video, etc. and transmits this information to the launch pad. The launch pad then searches whether a secure RM browser appropriate to handle this data is resident on the client. When it is determined that no RM browser is resident, the launch pad requests an appropriate browser from the RM server. Based on this request an appropriate RM browser is obtained and authentication and security information are inscribed. Thereafter the RM browser is transmited to the client. Prior …
