Description Tobie Langel 2012-01-24 22:23:11 UTC
Currently, the editor's draft allows preventing content from being cached by using the no-store http header. Often, developers cannot or do not know how to modify http headers to block sensitive parts of a website from being cached (when visited) by AppCache. e.g.:

A website containing both public and sensitive HTML pages needs to be made available offline. The sensitive data must not be stored on the device. The website is hosted on a virtual host and HTTP headers cannot be modified. The web developer can prevent such pages from being cached by specifying them directly in the manifest.
Comment 1 Ian 'Hixie' Hickson 2012-01-31 23:24:05 UTC
Why would any pages be cached if they're not listed in the manifest?

Also, who on earth is dealing with sensitive data yet can't change caching headers? That's a frightening thought.

They'd be cached as master entries simply by being visited.
