HTML5 Application Cache / PDF
Sample of the pdf document :
What is Application Cache?
HTML5 introduces application cache, which means that a web application is
cached, and accessible without an internet connection.
Application cache gives an application three advantages:
1.
Offline browsing -
users can use the application when they're offline
2. Speed - cached resources
load faster
3.
Reduced server
load - the browser will only download updated/changed resources from the server
Browser Support
Application cache is supported in all major browsers, except Internet
Explorer.
HTML5 Cache Manifest Example
The example below shows an HTML document with a cache manifest (for offline
browsing):
Example
<!DOCTYPE HTML>
<html manifest="demo.appcache">
<body>
The content of the document......
</body>
</html>
<html manifest="demo.appcache">
<body>
The content of the document......
</body>
</html>
Cache Manifest Basics
To enable application cache, include the manifest attribute in the
document's <html> tag:
<!DOCTYPE HTML>
<html manifest="demo.appcache">
...
</html>
<html manifest="demo.appcache">
...
</html>
Every page with the manifest attribute specified will be cached when the
user visits it. If the manifest attribute is not specified, the page will not
be cached (unless the page is specified directly in the manifest file).
The recommended file extension for manifest files is: ".appcache"
A manifest file needs to be served with the correct MIME-type, which is "text/cache-manifest". Must be configured on
the web server.
The Manifest File
The manifest file is a simple text file, which tells the browser what to
cache (and what to never cache).......
