html manifest attribute ADVANTAGES

Manifest appcache ADVANTAGES

The Advantages of using the manifest attribute are the following:

  1. less requests for server: cached resources are no longer requested to the Server; they are loaded from your pc, from Offline Cache Directory
  2. speed: resources stored on your local machine loads faster than those requested from Server
  3. webpages available offline: resources stored on your local machine don't need an Internet connection

The 3 advantages are demonstrated in the video tutorial below.
