[nsd-users] Multiple consumer catalog zones support in NSD

[Jeroen Koekkoek]

Hi Guillaume-Jean,

Sorry for not getting to this sooner! It escaped my attention. Willem's
the one who implemented it, but I believe this can be changed by means
of an undocumented compile time define
(MULTIPLE_CATALOG_CONSUMER_ZONES). At which point multiple consumer
zones are supported.

Note that it may cause problems if a member zone occurs in multiple
consumer zones though, which is why the define is there.

Hope that answers your question?

Best regards,
Jeroen
