Browser caching & Compression Εκτύπωση

  • Browser caching and gzip compression
  • 3

Browser caching (mod_expires) και gzip compression (mod_deflate) για οποιαδήποτε σελίδα δεν το υποστηρίζει από μόνη της.
Ο παρακάτω κώδικας επιτρέπει το caching αρχείων όπως jpg,png,js, css στον τοπικό υπολογιστή όπως και τη συμπίεσή τους ( mod_deflate / gzip compression ) για πιο γρήγορη εμφάνιση των σελίδων.
Αρκεί ο κώδικας να τοποθετηθεί στο κεντρικό .htaccess του public_html/ ή στον κεντρικό φάκελο της σελίδας αν πρόκειται για Addon / Sub Domain :

<IfModule mod_deflate.c>
