With app cache it is easy to make an offline version of a web application, by creating a cache manifest file.
What is App Cache?
HTML5 introduces application cache, which means that a web application is cached, and accessible without an internet connection.
Advantages:
- Offline browsing - users can use the application when they're offline
- Speed - cached resources load faster
- Reduced server load - the browser will only download updated/changed resources from the server
How to enable app cache?
To enable application cache, include the manifest attribute in the document's tag:
<!DOCTYPE HTML>
<html manifest="index.appcache">
...
</html>
Basic Example of HTML5 cache
This is our index.html file -
<!DOCTYPE html>
<html manifest="index.appcache">
<body>
<p>Content</p>
</body>
</html>
then we will create index.appcache file with below codes
CACHE MANIFEST
index.html
write those files that you want to be cached load index.html then go for offline mode and reload the tab.
Note: The two files must be in the same folder in this example.
