How do I leave Cache-Control public on my site?

Hello. my htaccess looks like this:

# BEGIN GZIP
<ifmodule mod_deflate.c>
    AddOutputFilterByType DEFLATE "application/atom+xml" \ "application/javascript" \ "application/json" \ "application/ld+json" \ "application/manifest+json" \ "application/rdf+xml" \ "application/rss+xml" \ "application/schema+json" \ "application/vnd.geo+json" \ "application/vnd.ms-fontobject" \ "application/x-font-ttf" \ "application/x-javascript" \ "application/x-web-app-manifest+json" \ "application/xhtml+xml" \ "application/xml" \ "font/eot" \ "font/opentype" \ "image/bmp" \ "image/svg+xml" \ "image/vnd.microsoft.icon" \ "image/x-icon" \ "text/cache-manifest" \ "text/css" \ "text/html" \ "text/javascript" \ "text/plain" \ "text/vcard" \ "text/vnd.rim.location.xloc" \ "text/vtt" \ "text/x-component" \ "text/x-cross-domain-policy" \ "text/xml"

However, my site is still with Cache-Control: no-cache, private.

Could you help me?
