clawbot	ae5445f70f	Leave SWWAF_RATE_LIMIT_EXEMPT_PATHS out of the request rate limits (closes #77) ... A request is neither counted nor refused by the request rate limits when its path, percent-decoded, starts with one of the comma-separated prefixes in SWWAF_RATE_LIMIT_EXEMPT_PATHS. A request whose decoded path contains .. or a backslash, or whose path as sent holds an encoded slash, is never exempt, since an app may act on it as a path outside every prefix, such as /assets/..%2Flogin as /login. The static lists, bans and the country lists still apply. The setting is empty by default, and a prefix that does not start with / stops the start. README.md documents it.

clawbot	73ca94f850	Ban the netblock of a client that breaks a rate limit, in memory (closes #18) ... A request over a rate limit is refused with SWWAF_BAN_RESPONSE and bans the client's netblock: an hour at first, three times the last ban when broken again within a day of its end, permanent past seven days. The ban ledger in internal/bans is checked after the static lists and before the lookup, and the requests it refuses are not counted. A ban resets the client's counters and carries notes holding the request that broke the limit, as SPEC.md now says. At most SWWAF_MAX_BANS are held. SWWAF_BAN_RESPONSE also answers SWWAF_DENY_NETS and the country lists. Judgement call: the six ban settings cannot be off. Judgement call: a permanent ban's ban_expires is "permanent".

clawbot	f51459fbfe	Per-client request rate limits over a minute, an hour and a day (closes #43) ... Each client, one IPv4 address or one IPv6 /64, is counted in two buckets per window, the earlier weighted by how much of it the window covers; at most 20,000 clients are kept, least recently seen dropped first. A request over SWWAF_RATE_LIMIT_PER_MINUTE, _HOUR or _DAY (1000, 10000, 50000, or off) gets 429 before reaching the app. Refused requests count, 413s included. A clock set back over a second behind a bucket's start restarts that window. The log line gains limit_hit and the action rate_limited. Deviation from SPEC.md, per the issue: the 20,000 bound and /64 are fixed. Judgement call: golang-lru/v2 holds the table; httprate does not count refused requests. Deviation: go.mod and go.sum hand-written; no make target tidies them. Model: opus-5-5	2026-10-04 04:24:34 +02:00
