* `max_streams` limits the number of concurrent QUIC streams per connection. This helps prevent unbounded streams on a single connection, exhausting server resources. The default value is 256 if not specified. Set to 0 to use underlying QUIC transport default.
* `max_connections` limits the number of concurrent HTTPS/3 connections accepted by the server. The default value is 200 if not specified. Connections above the configured limit are rejected. Set to 0 to disable the CoreDNS connection limit.
