Why is the browser cache not working?

Question

Apache HTTP Server

Good afternoon, there is a site on Bitrix, you need to enable the browser cache based on Google's recommendations.
As a result, in htaccess I insert:

<ifModule mod_expires.c>
    ExpiresActive On
    ExpiresDefault "access plus 5 seconds"
    ExpiresByType image/x-icon "access plus 1 month"
    ExpiresByType image/jpeg "access plus 4 weeks"
    ExpiresByType image/png "access plus 30 days"
    ExpiresByType image/gif "access plus 43829 minutes"
    ExpiresByType application/x-shockwave-flash "access plus 2592000 seconds"
    ExpiresByType text/css "access plus 604800 seconds"
    ExpiresByType text/javascript "access plus 604800 seconds"
    ExpiresByType application/javascript "access plus 604800 seconds"
    ExpiresByType application/x-javascript "access plus 604800 seconds"
    ExpiresByType text/html "access plus 43200 seconds"
    ExpiresByType application/xhtml+xml "access plus 600 seconds"
</ifModule>

Result 0, what could be the reason?

Answer 1

Do you have nginx before apache? If there is, and it is he who processes the statics, then your actions are useless.
