`dnsdist` can call Lua per packet if so configured, and will do so with the following hooks:
- * `bool blockfilter(ComboAddress, DNSName, qtype, DNSHeader)`: if defined, called for every function. If this
+ * `bool blockFilter(ComboAddress, DNSName, qtype, DNSHeader)`: if defined, called for every function. If this
returns true, the packet is dropped. If false is returned, `dnsdist` will check if the DNSHeader indicates
the packet is now a query response. If so, `dnsdist` will answer the client directly with the modified packet.
* `server policy(candidates, ComboAddress, DNSName, qtype, DNSHeader)`: if configured with `setServerPolicyLua()`
