В настоящее время мы работаем с сайтом:
Pressflow 5.23.50
Лак 2.1.4
Я подозреваю, что некоторые проблемы, с которыми я сталкиваюсь, основаны на большом разнообразии документации, и что некоторые из них актуальны, а некоторые нет.
В настоящее время я получаю следующие заголовки ответа:

Конфигурация лака:
Мы используем модуль Global Redirect, и я включил соответствующую проверку, которую я нашел в Интернете.

.host = "127.0.0.1";
.port = "7900";
# .connect_timeout = 600s;

## Modified from default to allow caching if cookies are set, but not http auth

return (pass);
}
## Remove has_js and Google Analytics cookies.
set req.http.Cookie = regsuball(req.http.Cookie, "(^|;\s*)(__[a-z]+|has_js)=[^;]*", "");
## Remove a ";" prefix, if present.

}
}
Я также добавил это в конец файла settings.php:
$conf['reverse_proxy'] = TRUE;
$conf['reverse_proxy_addresses'] = array('127.0.0.1');
У меня также есть Drupal, установленный на "Агрессивное кэширование" на странице производительности.
Есть какая-то маленькая вещь, по которой я скучаю, или, может быть, кто-то может указать мне на другие вещи, чтобы попробовать?
