2023-05-29[mod] limiter -> botdetection: modularization and documentationMarkus Heiser
In order to be able to meet the outstanding requirements, the implementation is modularized and supplemented with documentation. This patch does not contain functional change, except it fixes issue #2455 ---- Aktivate limiter in the settings.yml and simulate a bot request by:: curl -H 'Accept-Language: de-DE,en-US;q=0.7,en;q=0.3' \ -H 'Accept: text/html' -H 'User-Agent: xyz' \ -H 'Accept-Encoding: gzip' \ 'http://127.0.0.1:8888/search?q=foo' In the LOG: DEBUG searx.botdetection.link_token : missing ping for this request: ..... Since ``BURST_MAX_SUSPICIOUS = 2`` you can repeat the query above two time before you get a "Too Many Requests" response.
