<!--
When the web console sits behind a reverse proxy or load balancer,
uncomment the customizer below so Jetty honors X-Forwarded-* (or
RFC 7239 Forwarded) headers when populating request.getRemoteAddr(),
request.getScheme(), etc. This is what gets the real client IP into
access logs and audit trails.

WARNING: ForwardedRequestCustomizer trusts these headers from any
client. Only enable it when the upstream proxy strips inbound
X-Forwarded-* headers, otherwise a remote client can spoof its
source IP and apparent scheme.

Note: this does NOT change InetAccessHandler's filtering — that
handler always evaluates the socket peer (the proxy itself) and
ignores forwarded headers. In a proxied deployment either keep the
allow list scoped to the proxy address and rely on the proxy for
client-IP filtering, or remove InetAccessHandler entirely.

IP-based access control for the web console.
Patterns accept: exact IP (192.168.1.1), CIDR (10.0.0.0/8),
range (10.0.0.0-10.255.255.255), or qualified with path/connector
using '|' (e.g. 192.168.1.0/24|/api).
Exclude rules take precedence over include rules.
With the default host binding of 127.0.0.1, only localhost is reachable;
if the bind address is broadened (e.g. 0.0.0.0), add explicit include
entries below for the networks that should reach the console.
