Programmatically invalidating cached pages

This restricts the URLs to which the manifest is applied and provides a means to "deep link" into a web application from other applications.Using this metadata, user agents can provide developers with means to create user experiences that are more comparable to that of a native application.If you have many assets and lots of traffic, those requests could result in a substantial increase in requests to your origin and slow down your website.To purge everything from cache, visit the caching app in the Cloudflare dashboard.Purging the entire cache means all resources in Cloudflare's cache are immediately invalidated and the subsequent request for each invalidated resource will go back to your origin server(s) in an attempt to revalidate the resource.If the resource can't be revalidated, the resource in Cloudflare's cache will be replaced with the newer version of the resource from your origin.Main difference is that it is done through observer and the code is wrapped up in extension for easier use.

You set cache expiration using the caching profiles, described above.

The manifest also allows developers to declare a default orientation for their web application, as well as providing the ability to set the display mode for the application (e.g., in fullscreen).

Additionally, the manifest allows a developer to "scope" a web application to a URL.

This specification defines a JSON-based manifest file that provides developers with a centralized place to put metadata associated with a web application.

This metadata includes, but is not limited to, the web application's name, links to icons, as well as the preferred URL to open when a user launches the web application.
