#HAProxy vs The LLM Bot army
Because it’s holidays I am off thinking of crazy hacking ideas..
What about combining #JA4+ TLS fingerprinting with HAProxy to try to drop residential bot swarms?
https://github.com/FoxIO-LLC/ja4
The idea is that a bot lies about its identity - the TLS library and the user agent header don’t match up. They say they’re latest chrome browser but it’s actually some weird python library.
So if you compute the used TLS fields, you can see if that matches the user agent or not.
Read https://tracio.ai/blog/tls-fingerprinting-ja4 for a longer explanation.
It turns out others have already made great progress on this:

nginx не умеет reload. Он умеет fork
Деплой делает nginx -s reload . Команда возвращает ноль, nginx -T показывает новый конфиг, в error.log ровно одна строка — reconfiguring. А keep-alive соединение, открытое секундой раньше, в этот момент закрывается. Само по себе это не ошибка: сервер вправе закрыть простаивающий keep-alive когда угодно. Ошибку даёт гонка — FIN уходит в тот момент, когда клиент уже записал в сокет следующий запрос. Идемпотентный он повторит, POST — нет. Разбор по исходникам на фиксированных тегах: nginx release-1.31.3, httpd 2.4.68, traefik v3.7.10, плюс замер всех четырёх (с HAProxy) на одном стенде в одном прогоне. Выясняется, что мастер nginx конфиг не перечитывает вообще: он строит новый цикл целиком и форкает новых воркеров, а старым остаётся ровно то, что у них было. Apache приходит к тому же контракту через счётчик поколений, HAProxy — через замену процесса. А у одного из четырёх второй запрос в том же самом сокете возвращает уже новый конфиг — и причина не та, о которой вы подумали. Внутри: почему документация nginx сама создаёт половину недоразумения; почему WebSocket и SSE не попадают под ngx_close_idle_connections и держат старого воркера сколько угодно долго, а HTTP/2 попадает всегда и получает GOAWAY; как сигнал родителя у Apache доезжает до конкретного соединения через пять звеньев; и таблица из двенадцати клеток, в которой четыре реализации расходятся ровно в одной. Со стендом (один docker build, один docker run), полными выводами ps и тремя claims-*.tsv, где каждое утверждение о коде проверяется скриптом.

He encontrado este repositorio https://github.com/ai-robots-txt/ai.robots.txt que ofrece varios ficheros de configuración actualizados para diferentes servidores web (#Apache, #nginx, #caddy, #lighthttpd y #haproxy) y un robots.txt que bloquean varios "AI Crawlers" o "scrappers" por user-agent para evitar que abusen de vuestro servidor. Evidentemente esto no es infalible porque bien es sabido que no respetan nada, pero menos da una piedra y la configuración es mínima y quirúrgica.

I've been messing around with #Ansible again. My old #HAProxy setup was way too clunky when it came to managing #TLS certificates. With my new playbook, all domain names in my inventory file get TLS certs automatically provisioned and primed for automatic renewal.

Day 17/60: HAProxy fundamentals
Dug into stick tables for in-memory rate limiting. You define a table with http_req_rate, track source IPs, and deny with 429 status. All inside the HAProxy config.
Also explored the runtime socket API for zero-downtime deploys: drain a server, wait for connections to close, deploy, bring it back. One socat command each step.
Health check tuning matters more than people realize. inter 3s fall 3 rise 2 is a solid baseline.

Day 15/60: Load balancing algorithms
Connection draining is what separates clean deploys from dropped requests. You stop sending new connections to the target server and let all existing in-flight requests finish gracefully.
HAProxy slowstart ramps traffic to recovered servers over 30 seconds instead of hitting them at full weight immediately. Cold JVM heaps and empty connection pools need that ramp.
Combine draining + slowstart = zero-downtime deployments without overloading fresh backends.
