Every proxied request flows through one shared OpenResty location whose behavior is chosen at request time from the host's Redis hash. Add per-host controls as new Host fields enforced in Lua rather than static nginx config (which can't key off a per-request variable): - Rate limiting: per-client-IP token bucket via resty.limit.req (ratelimit_enabled/rate/burst), backed by a new `ratelimit` shared dict. - Response caching: opt-in per host via a global proxy_cache zone gated by $skip_cache (respcache_enabled). Off by default; upstream Cache-Control still honored. - Custom/security headers: req_headers (upstream) + resp_headers (client) and hsts_enabled, applied in access/header_filter phases. - IP allow/deny CIDR lists via resty.ipmatcher (deny wins; non-empty allow is default-deny). New ops/nginx_conf/hostfeatures.lua holds the enforcement; proxy.conf's access_by_lua string becomes a block that calls it, plus a header_filter block. nodejs/utils/host_features.js is the pure, unit-tested normalize/validate layer (header/CIDR parsing, range clamping, injection-safe values) applied in routes/host.js and mirrored by the hosts.ejs edit form. install.sh gains the ipmatcher rock, the cache dir, and the hostfeatures.lua symlink. Per-host cache TTL is intentionally deferred (global default only) — see the plan's limitations. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
