  dedicated to CDMnet that are isolated from their
  Internet servers.
• A user will not be able to click on a link and
  get routed to some other site on the Internet
• That is, routing to the Internet will not be
  allowed through the DataGate.
• While Java is not used on the DataGate, it might
  be used on sites that the DataGate links to.
• There are only links to trusted sources.
• An airline could disable Java if it wished.
