Summary

Added domain name creation example with ROUTING_RULE_ONLY mode and TLS 1.2 configuration

Security assessment

The change documents security policy configuration (TLS_1_2) as part of a routing mode example, but shows standard security practices rather than addressing a vulnerability. The primary focus is on routing configuration.
