ExpiresByType «доступ плюс 1 месяц» приводит к истечении 1 года заголовок

Я реализовал истечение срока действия ресурса со следующей настройкой

<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/gif "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType application/pdf "access plus 1 month"
    ExpiresByType application/x-javascript "access plus 1 month"
    ExpiresByType text/javascript "access plus 1 month"
    ExpiresByType application/x-shockwave-flash "access plus 1 month"
    ExpiresByType image/x-icon "access plus 1 year"
    ExpiresDefault "access plus 2 days"
</IfModule>

с истечением срока действия a2dismod, как и ожидалось, у меня нет заголовка Expires:

с a2enmod истекает, но я получаю ответ истекает через 1 год

Я также запустил grep, чтобы найти любые другие инструкции истечения срока действия, но их нет.

После добавления приложения ExpiresByType / x-javascript проблема все еще сохраняется. Мог ли быть конфликт с deflate?

ubuntu@sandbox:/etc/apache2$ grep -r application/x-javascript *
mods-available/deflate.conf:        AddOutputFilterByType DEFLATE     application/x-javascript application/javascript application/ecmascript
