Шпаргалка: Настройка mod_expires.c

В двух словах, настройка модуля позволяет установить кеширование статики браузером. 
Настройки от Битрикс по умолчанию довольно скудны (в .htaccess): 

<IfModule mod_expires.c>
   ExpiresActive on
   ExpiresByType image/jpeg "access plus 3 day"
   ExpiresByType image/gif "access plus 3 day"
</IfModule>

Этого явно мало. Поэтому я предлагаю такой вариант:

<IfModule mod_headers.c>
    Header unset ETag
</IfModule>
 
<IfModule mod_expires.c>
    ExpiresActive on
    ExpiresDefault                                      "access plus 1 week"
