В нашем офисе мы используем squid, чтобы запретить пользователям подключаться только к определенным веб-сайтам и URL-адресам. Если пользователь подключается к веб-странице через https, url_regex acl не будет работать. В запросе https мы имеем контроль только над доменом. Но нам нужно ограничить на уровне URL. Итак, мы использовали ssl bump для перехвата https-запросов. Он работает нормально, но мы получили несколько предупреждений ssl в браузере.
Возможно ли перехватить ssl-соединение в Bump без каких-либо предупреждений браузера?
