HTTPS/3 uses QUIC as the underlying transport. This plugin can only be used once per HTTPS3 listener block. Syntax https3 { max_streams POSITIVE_INTEGER } 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.
