Why are mod_headers.c and mod_expires.c not processed?

Question

Apache HTTP Server

Good afternoon. Can you please tell me
why mod_headers.c and mod_expires.c are not processed in the .htaccess file
Apache Version Apache / 2.2.16 (Debian)
mod_expires mod_headers mod_include mod_mime mod_negotiation mod_php5 mod_reqtimeout mod_rewrite mod_setenvif mod_status mod_vhost_alias
Modules hang in loaded modules. I checked the processing of the .htaccess file. Processing.
And if you add

<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access 7 days"
ExpiresByType application/javascript "access plus 1 year"
ExpiresByType text/javascript "access plus 1 year"
ExpiresByType text/css "access plus 1 year"
ExpiresByType text/html "access plus 7 day"
ExpiresByType text/x-javascript "access 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/x-icon "access 1 year"
ExpiresByType application/x-shockwave-flash "access 1 year"
</IfModule>

or

<ifModule mod_headers.c>
# 30 дней
<filesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>
# 30 дней
<filesMatch "\.(css|js)$">
Header set Cache-Control "max-age=2592000, public"
</filesMatch>
# 2 дня
<filesMatch "\.(xml|txt)$">
Header set Cache-Control "max-age=172800, public, must-revalidate"
</filesMatch>
# 1 день
<filesMatch "\.(html|htm|php)$">
Header set Cache-Control "max-age=172800, private, must-revalidate"
</filesMatch>
</ifModule>

Doesn't want to be done, no matter how.
Tell me, in which direction to dig?
