[10.2][hdrs] HTTP QUERY method not registered as a well-known method

Branch: 10.2.x (10.2.1, commit 31f1f2f3b) · Severity: low · category: missing-feature
Location: src/proxy/hdrs/HdrToken.cc:113, src/proxy/hdrs/HTTP.cc:147-178

What's wrong

The well-known method table lists only CONNECT, DELETE, GET, POST, HEAD, OPTIONS, PURGE, PUT, TRACE, PUSH. QUERY (draft-ietf-httpbis-safe-method-w-body — a safe, cacheable method with a request body) is not recognized, so it is handled as an unknown method and can't be matched by ip_allow/remap ACLs, per-method stats, or plugins.

Fix

Register QUERY in the hdrtoken method table and the HTTP_METHOD_* / HTTP_WKSIDX_* set. Caching of QUERY responses is intentionally left unchanged (a correct cache key must incorporate the request-content digest per the draft). PR attached.

Testing

Compiles cleanly on 10.2.x; test_proxy_hdrs passes. The method WKS indices stay contiguous (ip_allow's 32-bit method mask has ample room for an 11th method). clang-format clean.

From an automated multi-lens audit of the 10.2.x branch. Full report on branch claude/codebase-audit-review-9nw7vz (CODEBASE_AUDIT_10.2.md).

Start with the method tables in src/proxy/hdrs/HdrToken.cc:113 and src/proxy/hdrs/HTTP.cc:147-178, then inspect nearby method definitions and index ordering. Confirm QUERY is represented consistently and run test_proxy_hdrs; done means the method is recognized for ACLs, statistics, and plugins while the existing caching behavior remains unchanged.
