Есть ли способ в Windows запретить одному и тому же IP-адресу открывать одну и ту же страницу повсюду?

Это законно, и мне показалось странным, что используется тот же процесс ...
Я предлагаю выполнить быстрый поиск в Google, так как похожие вопросы задавались много раз раньше.
Mod_security хорошо подходит для вашей проблемы:
SecRuleEngine On
SecAction initcol:ip=%{REMOTE_ADDR},pass,nolog
SecAction "phase:5,deprecatevar:ip.somepathcounter=1/1,pass,nolog"
SecRule IP:SOMEPATHCOUNTER "@gt 20" "phase:2,pause:300,deny,status:509,setenv:RATELIMITED,skip:1,nolog"
SecAction "phase:2,pass,setvar:ip.somepathcounter=+1,nolog"
Header always set Retry-After "10" env=RATELIMITED
ErrorDocument 509 "Rate Limit Exceeded"
Вы должны рассчитать соответствующие пределы, чтобы избежать ложных срабатываний.
