HEAD
- Retrieval of requestor's IP address centralized in lonnet::get_requestor_ip()
- Domain configuration to allow domain's LON-CAPA nodes to operate behind a
WAF/Reverse Proxy using aliased hostname (CNAME).
- Web requests from other nodes bypass the WAF as their requests are made
directly to the server hostname (A record); same for internal LON-CAPA
connections for lonc -> lond.
