Has there been any thought into having CFE do failover based on a given name returning multiple IP addresses? Lets say www.yahoo.com was hosting my CFE server:
# host www.yahoo.com www.yahoo.com is an alias for www.yahoo.akadns.net. www.yahoo.akadns.net has address 68.142.197.85 www.yahoo.akadns.net has address 68.142.197.64 www.yahoo.akadns.net has address 68.142.197.65 www.yahoo.akadns.net has address 68.142.197.67 www.yahoo.akadns.net has address 68.142.197.68 www.yahoo.akadns.net has address 68.142.197.76 www.yahoo.akadns.net has address 68.142.197.80 www.yahoo.akadns.net has address 68.142.197.83 Cfagent could iterate over the whole list trying to perform a copy, instead of requiring the user to add a 'failover=' line (which is therefore limited to just 2 potential sources). One could even expand on that to have it randomly choose from the list or do some sort of check (ie ping) to try them in some order. This would be very handy when one has CFE clients on opposite ends of a 3-way WAN pipe with a CFE server on each end. Clients would pick the best available server and fail over to the next best on down until they get one that worked. I realize one can do this now in a basic form by determining the server value based on the current subnet, but this limits one to only a 2-way failover. Something more flexible would be handy.
