}

Specifies the match criteria for selecting a specific filter chain for a listener.

In order for a filter chain to be selected, *ALL* of its criteria must be fulfilled by the incoming connection, properties of which are set by the networking stack and/or listener filters.

The following order applies:

1. Destination port. 2. Destination IP address. 3. Server name (e.g. SNI for TLS protocol), 4. Transport protocol. 5. Application protocols (e.g. ALPN for TLS protocol).

For criterias that allow ranges or wildcards, the most specific value in any of the configured filter chains that matches the incoming connection is going to be used (e.g. for SNI “www.example.com“ the most specific match would be “www.example.com“, then “*.example.com“, then “*.com“, then any filter chain without “server_names“ requirements).

[#comment: Implemented rules are kept in the preference order, with deprecated fields listed at the end, because that's how we want to list them in the docs.

[#comment:TODO(PiotrSikora): Add support for configurable precedence of the rules]
