From b8c7c2c9aa604fd1fb7be5559c9ad025ceb17aa4 Mon Sep 17 00:00:00 2001 From: Markus Heiser Date: Sun, 28 May 2023 18:58:31 +0200 Subject: [mod] botdetection - improve ip_limit and link_token methods - counting requests in LONG_WINDOW and BURST_WINDOW is not needed when the request is validated by the link_token method [1] - renew a ping-key on validation [2], this is needed for infinite scrolling, where no new token (CSS) is loaded. / this does not fix the BURST_MAX issue in the vanilla limiter - normalize the counter names of the ip_limit method to 'ip_limit.*' - just integrate the ip_limit method straight forward in the limiter plugin / non intermediate code --> ip_limit now returns None or a werkzeug.Response object that can be passed by the plugin to the flask application / non intermediate code that returns a tuple [1] https://github.com/searxng/searxng/pull/2357#issuecomment-1566113277 [2] https://github.com/searxng/searxng/pull/2357#discussion_r1208542206 [3] https://github.com/searxng/searxng/pull/2357#issuecomment-1566125979 Signed-off-by: Markus Heiser --- searx/botdetection/http_accept.py | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'searx/botdetection/http_accept.py') diff --git a/searx/botdetection/http_accept.py b/searx/botdetection/http_accept.py index 23670a283..60e2330ae 100644 --- a/searx/botdetection/http_accept.py +++ b/searx/botdetection/http_accept.py @@ -15,13 +15,15 @@ Accept_ header ..
