The package passes nothing to an app since rproxy took that over, so it
is named after the command it serves. Its constructor is New, like
rproxy's. The rproxy tests call their stand-in for servewaf standIn,
since a local servewaf would hide the package. No change of behaviour.
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.
