2023-04-13[mod] limiter: block unmaintained Farside instancesMarkus Heiser
Since [bb3a01f8] has been merged to the Farside project, Farside instances do no longer need to send requests to SearXNG instances [1]. There are some old unmaintained Farside instances on the web that continue to query SearXNG instances --> we can safely block their requests.

2023-04-01[mod] limiter: minor improvementsMarkus Heiser
- requests without HTTP header 'Connection' or missing 'User-Agent' will be blocked by the limiter - re_bot is related to 'User-Agent' and has been renamed to block_user_agent Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
2023-04-01[mod] plugin limiter: improve the log messagesMarkus Heiser
In debug mode more detailed logging is needed to evaluate if an access should have been blocked by the limiter. BTW: remove duplicate code checking bot signature ``re_bot.match(user_agent)`` Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

Remove the abstraction in searx.shared.SharedDict. Implement a basic and dedicated scheduler for the checker using a Redis script.
2022-08-25[mod] limiter plugin: Accept-Encoding handlingLéon Tiekötter
Only raise "suspicious Accept-Encoding" when both "gzip" and "deflate" are missing from Accept-Encoding. Prevent Browsers which only implement one compression solution from being blocked by the limiter plugin. Example Browser which is currently blocked: Lynx Browser (https://lynx.invisible-island.net)
