Trying to set a simple fail over when site A is active and site B is
standby. When A fails all traffic goes to B. Should be pretty easy
with SRV records but my experimental BIND server does not deliver the
expected result. Also i am not sure if these records are implemented
in IE7 or Firefox.
Aslo any suggestions on how to support multiple grographically dispersed web
servers are welcome.
Here is the zone file:
$TTL 86400

5 ; serial number YYMMDDNN
28800 ; Refresh

)
