Is this possible? (auto-redirect if server is down)
I am thinking of this possibility:
A site domain.com is hosted in host A. Another site domain.net is hosted in host B.
Both domain.com and domain.net are registered under one registrar. The registrar offers URL forwarding feature.
Scenario:
A visitor goes to domain.com but host A which is hosting domain.com is down.
As a consequence, the visitor should be redirected to domain.net which is hosted by host B. A visitor can directly visit domain.net. But, we don't want that. We only want domain.net accessible if domain.com is down. In other words, domain.net "only exists" if domain.com "dies".
Questions:
1. Is the scenario possible?
2. How is the configuration set that instructs the server (or something) that will direct visitors to domain.net if domain.com is down?
3. How is the configuration set so that domain.net only allow access to its contents when domain.com is down?
4. What is done with the registrar's control panel?
Thanks in advance for the help.
BEGIN ADDED INFO:
For info, the registrar is Stargate. Here is their reply to a recent query:
"The only way I could see that happening is if you change your nameservers to Stargates only. Then activate URL Forwarding for domain.com to http://www.domain.net/. Once that has been activated, then make your primary and secondary nameserver YOURS, then make your 3rd and 4th nameserver OURS. This has not been done before so I can guarantee no results whatsoever."
