Fixes#47.
- Added lua-resty-balancer to dependencies (Dockerfile & install.sh).
- Added 'targets' field to the Host model to hold additional targets.
- Updated the UI to allow inputting additional targets (IP:port).
- Updated targetinfo.lua to parse the additional targets and load balance between them and the primary target using resty.balancer.round_robin.
Adds opt-in basic auth per Host, following the existing per-host controls
pattern:
- Host fields basicauth_enabled / basicauth_realm / basicauth_users
({user: base64(sha1(pw))}). Credentials are parsed to plaintext by the pure
host_features normalizer and hashed at the route layer (utils/basicauth.js),
so plaintext never reaches Redis.
- ops/nginx_conf/hostfeatures.lua enforces it in access phase: verifies the
Authorization header against base64(sha1(password)), fails closed with a 401
WWW-Authenticate challenge.
- hosts.ejs gains an enable toggle, realm, and a username:password textarea
(passwords never echoed back; blank keeps the current set).
Unit tests cover hashing (matches the htpasswd {SHA} vector), credential
parsing, and normalization. Note: the Lua path needs verification on a live
OpenResty box.

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.
