Добрый времени суток такой вопрос.
У меня на vps стоит apache + nginx
Мне необходимо кэшировать данные, прочитал статьи
docs.moodle.org/archive/ru/%D0%9D%D0%B0%D1...

#! Статический контент! location ~* \.(jpg|jpeg|gif|png|swf|tiff|swf|flv)$ { root $webroot; #Кеширум картинки месяца на 4 expires 4M; #Кешируем везде (и на прокси и на клиентах) add_header Cache-Control public; }
в примере осуществляется кеширование на стороне как клиента так и промежуточных серверов. переменная $webroot указывает, где находиться папка с файлами moodle, например:
set $webroot '/var/www/moodle'; root $webroot;
этого момента я не до конца не догоняю, куда он ссылаться должен??
