html manifest attribute ADVANTAGES
Manifest appcache ADVANTAGES
The Advantages of using the manifest attribute are the following:
- less requests for server: cached resources are no longer requested to the Server; they are loaded from your pc, from Offline Cache Directory
- speed: resources stored on your local machine loads faster than those requested from Server
- 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.
