Is AppCache = Application Cache = Web Storage's LocalStorage?

阅读更多关于 Is AppCache = Application Cache = Web Storage's LocalStorage?

问题 I'm getting a bit confused by the (varied) terminology for HTML5 offline storage. I think that AppCache is another name for Web Storage and you specify what will be stored offline via the Cache Manifest. And there are two types: LocalStorage (persists beyond the current session) and session storage (which does not persist beyond the current session). The above is what I'm reading from W3C and from wikipedia but Head First HTML5 Programming (Freeman & Robinson) describes LocalStorage in depth,

Is Service Worker intended to replace or coexist with Appcache?

阅读更多关于 Is Service Worker intended to replace or coexist with Appcache?

问题 Is ServiceWorker intended to replace Appcache, or is the intention that the two will coexist? Phrased another way, is appcache about to become deprecated? 回答1: Blink's Service Worker team is keen on deprecating AppCache (We will follow our usual intent to deprecate process). We believe that Service Worker is a much better solution. Also, it should be pretty easy to offer a drop-in replacement for AppCache built on top of SW. We'll start by collecting usage metrics and do some outreach.

Removing HTML5 Appcache Manifest, Permanently

阅读更多关于 Removing HTML5 Appcache Manifest, Permanently

问题 I setup an Application Cache on a site and shortly thereafter realized its way more aggressive that I realized. I want to remove it. Permanently. I've read that passing a changed manifest file, completely empty, with the correct MIMETYPE will remove the cache. Edit: See below. Maurice's answer is the only consistent fix. Is this the fastest, most effective solution? Is there a better way? And if you can specify whether or not you've actually used this functionality before with your answer I'd

UPDATE: ** I posted this question when this feature was really new, I realize now that this feature should not be used this way unless it is used via JavaScript. but seems like this hack is a great solution for most beginners who make the same mistake and misuse of this feature. If you want to cache everything except your HTML this should be done with JS or you could use the solution below ** I guess my question boils down to this: If the file referencing the manifest using the manifest attribute of the HTML tag falls under the MASTER CACHE ENTRIES how could you have a dynamic page use the

Can local storage ever be considered secure? [closed]

阅读更多关于 Can local storage ever be considered secure? [closed]

I'm required to develop a web application that will function offline for long periods. In order for this to be viable I cannot avoid saving sensitive data (personal data but not the kind of data you would only store hashed) in local storage. I accept that this is not recommended practice, but given little choice I'm doing the following to secure the data: encyrypting everything going into local storage using the stanford javascript crypto library and AES-256 the user password is the encryption key and is not stored on the device serving all content (when online) from a single trusted server
