A visitor could get a closed connection and no answer when
SWRP_MAX_RESPONSE_TIME_MS ran out about when the answer started: the
write deadline passed before the first byte was written.
- An answer rproxy gives itself has at least 10 seconds to be sent.
- An app's answer that arrives once the time has run out is answered
504.
- Otherwise the app's status and headers are sent at once, before the
body is read, with at least 10 seconds. The exact limit applies to
the rest.
Model: opus-5-5
`smallwebwaf rproxy` reads the first 64 KiB of each body, asks servewaf over
HTTP/1.1, and passes what servewaf allows to the app within its limits. Any
other answer goes to the visitor as servewaf gave it. SWRP_DEFAULT_DISPOSITION
decides only when servewaf cannot be connected to, does not answer at all, or
does not answer within SWRP_TIMEOUT_MS. A method SPEC.md does not list gets 405.
Duplication: internal/rproxy copies passing-on code from internal/proxy until
#172 removes the originals.
Rule suppressed: gosec G704 and G705; gosec at
internal/smallwebwaf/rproxy_test.go:431; tagliatelle at
internal/requestlog/requestlog.go:203; paralleltest on one test.
Judgement call: an answer over 1 MiB, or with a status below 200, gets 502.
Judgement call: every target not starting with one / gets 400.
