All, I am wondering if it's possible to issue >1 command over the SSL control channel? Specifically "flush" commands for >1 host. I might want to flush anything from 1-1000 specific hosts from the cache (most commonly 2-10) every few minutes. Background: We run a set of bind 9 servers as our recursive resolvers. These servers also stealth slave our own zones, which are updated by DDNS from our database. NOTIFY & IXFR therefore ensure the recursive servers always have a "correct" copy of our data, to within a few minutes at most. I am considering a move away from this model, and was initially reluctant to look at unbound because of the difficulty of maintaining this stealth slave. However it then occurred to me that I could simply "flush" the changed names inside the master update process, since I know what they are. I don't really want to either lower the TTL or run a 2nd low-TTL copy of our master zones. From a quick glance the source code seems only to take a single command over the socket; would an attempt at a patch be accepted or useful? Cheers, Phil
