Environment
If the RX document requests X-UI-LBX service and the default X server does not advertise the LBX
extension, the RX Plugin will look for the environment variable XREALDISPLAY to get a second
address for your X server and look for the LBX extension there. When running your browser through
lbxproxy you will need to set XREALDISPLAY to the actual address of your server if you wish remote
applications to be able to use LBX across the Internet.
If the RX document requests XPRINT service, RX Plugin looks for the variable XPRINTER to get the
printer name and X Print server address to use. If the server address is not specified as part of
XPRINTER, RX Plugin uses the first one specified through the variable XPSERVERLIST when it is
set. When it is not RX Plugin then tries to use the video server as the print server. If the printer name is
not specified via XPRINTER, RX Plugin looks for it in the variables PDPRINTER, then LPDEST, and
finally PRINTER.
Notes
When an authorization key is created for a remote application to use the X Print service, the RX Plugin
has to create the key with an infinite timeout since nobody knows when the application will actually
connect to the X Print server. It then revokes the key when its instance is destroyed (that is when you go
to another page). However, if the plugin does not get destroyed properly, which happens when Netscape
Navigator dies unexpectedly, the print authorization key will never get revoked.
