Ports the SOCKS5 + fallback-chain design from @masterking32's
MasterHTTP-WithSOCKS branch so xray / Telegram / app-level TCP
clients work through this proxy.
Changes:
- New SOCKS5 listener on listen_port+1 (configurable via socks5_port)
- RFC 1928 CONNECT handshake (v5, no-auth, ATYP IPv4/domain/IPv6)
- Shared smart dispatch with the HTTP-CONNECT path
- Unified dispatch_tunnel() used by both CONNECT entry points:
1. If host matches SNI-rewrite suffix or hosts override: go direct
to google_ip via the MITM+TLS tunnel (fast path for google.com,
youtube, etc.)
2. Peek the first byte (300ms timeout for server-first protocols):
- 0x16: TLS client hello -> MITM + relay via Apps Script (scheme=https)
- HTTP method signature: HTTP relay via Apps Script (scheme=http)
- Anything else or timeout: plain TCP passthrough to the target
- handle_mitm_request() now takes a scheme arg (http/https) so the
same code path handles both MITM'd HTTPS and port-80 plain HTTP
- New plain_tcp_passthrough helper: bidirectional TCP bridge used as
the final fallback (covers MTProto / raw TCP / server-first protos)
Config:
- Added optional socks5_port field; defaults to listen_port+1
README:
- Added browser vs xray/Telegram instructions under 'Step 6'
Live-tested: HTTP proxy, HTTP proxy -> HTTPS, SOCKS5 -> HTTP,
SOCKS5 -> HTTPS, Google search via SNI-tunnel (now returns full
JS page) all pass.
test: one-shot end-to-end probe. Issues a GET to api.ipify.org through
the configured relay and prints status + body + timing. Clear pass/fail
with specific diagnostics for 502/504 (auth_key mismatch, quota, etc).
Verified live: 3.8s round-trip returning the caller's real IP.
scan-ips: parallel TLS probe of 28 known Google frontend IPs with
SNI=front_domain. Reports which are reachable and sorts by latency.
Users pick the fastest and paste into google_ip. Verified live:
7/28 reachable (the others were Windscribe'd out), top 3 ranked.
Both subcommands share the existing config.json and require no extra
flags. Default 'mhrv-rs' with no subcommand runs the proxy as before.
- New cache.rs: FIFO-eviction cache with max_bytes cap
- Cacheable: GET/HEAD only, no-store/no-cache/private/Set-Cookie reject
- TTL from Cache-Control: max-age=, or heuristics by extension (css/js/fonts/images -> 1h)
- Hook in DomainFronter::relay: check cache before network, store after 2xx
- 10 new unit tests (23 total)
