Apache Cache Headers

Here are some nice Apache configuration entries that will increase your website performance. They can be placed in a .htaccess file:

<IfModule mod_headers.c>
  ##
  # Add a Vary Accept-Encoding header for the compressed resources. If you
  # modify the file types above, make sure to change them here accordingly.
  ##
  Header unset ETag
  #  Header set Cache-Control "no-cache" -> Cache aus
  <FilesMatch "\.(ico|jpg|jpeg|png|gif|js|css)$">
    Header unset Last-Modified
    Header append Cache-Control "public, max-age=3600"
  </FilesMatch>
  <FilesMatch "\.(html)$">
    Header unset Last-Modified
    Header append Cache-Control "public, max-age=60"
  </FilesMatch>
  #  <FilesMatch "\.(js|css|xml|gz)$">
  #    Header append Vary Accept-Encoding
  #  </FilesMatch>
  #  <FilesMatch "\.(ttf|otf|eot|woff|svg)$">
  #    Header set Access-Control-Allow-Origin "*"
  #  </FilesMatch>
</IfModule>
 
<IfModule mod_expires.c>
