How to cache a website with an .htaccess file?

Browser caching

Using mod_expires, you can tell visiting browsers to hold on to certain files longer (likes images, which are rarely changed).

# BEGIN Expire headers  
<IfModule mod_expires.c>  
  # Turn on the module.
  ExpiresActive on
  # Set the default expiry times.
  ExpiresDefault "access plus 2 days"
  ExpiresByType image/jpg "access plus 1 month"
  ExpiresByType image/svg+xml "access 1 month"
  ExpiresByType image/gif "access plus 1 month"
  ExpiresByType image/jpeg "access plus 1 month"
  ExpiresByType image/png "access plus 1 month"
  ExpiresByType text/css "access plus 1 month"
  ExpiresByType text/javascript "access plus 1 month"
  ExpiresByType application/javascript "access plus 1 month"
  ExpiresByType application/x-shockwave-flash "access plus 1 month"
  ExpiresByType image/ico "access plus 1 month"
  ExpiresByType image/x-icon "access plus 1 month"
  ExpiresByType text/html "access plus 600 seconds"
</IfModule>  
# END Expire headers
