Appendix G: RX Helper Program
Name
xrx: RX Helper Program
Synopsis
xrx
Description
The helper program may be used with any Web browser to interpret documents in the RX MIME type format and start remote applications.
xrx reads in the RX document specified by its <filename>, from which it gets the list of services the application wants to use. Based on this information, xrx sets the various requested services, including creating authorization keys if your X server supports the SECURITY extension. It then passes the relevant data, such as the X display name, to the application through an HTTP GET request of the associated CGI script. The Web server then executes the CGI script to start the application. The client runs on the web server host connected to your X server.
