✓ How it works: - Etag – Tells browsers that an image/unit does not need to be reloaded- Expires Headers – Set different expiration dates for various file types- AddOutputFilterByType DEFLATE – minifies the compiled HTML source code
Some .htaccess Magic
✓ The code:
FileETag MTime Size AddOutputFilterByType DEFLATE text/html text/css application/javascript ExpiresActive On ExpiresDefault "now plus 1 hour" ExpiresByType text/css "now plus 1 week“ExpiresByType application/javascript "now plus 1 week" ExpiresByType application/x-javascript "now plus 1 week”
