我能够缓存本地文件(图像,js等)完美无瑕。我可以从HTML5应用程序缓存中加载网络资源吗?
理想情况下,我希望能够指向存储在Azure上的blob存储中的远程资源,如.mp4,并缓存该资源。那可能吗?
我在日志中没有看到任何错误,但我也没有看到它正在被下载,因为它在Chrome浏览器 - >资源面板下的应用程序缓存中不可用。

这就是我如何保持一个记录正在发生的事情:
// App cache validation
var appCache = window.applicationCache;
if (appCache === null || undefined) {
console.log("App cache does not exist");
}
appCache.addEventListener('checking', function(event) {
console.log("Checking for updates.");
}, false);
appCache.addEventListener('error', function(event) {
if (navigator.onLine === true) { //If the user is connected to the internet.
//alert("Error - Please contact the website administrator if this problem consists.");
console.log("Error - Please contact the website administrator if this problem consists.");
} else {
//alert("You aren't connected to the internet. Some things might not be available.");
console.log("You aren't connected to the internet. Some things might not be available.");
}
}, false);
appCache.addEventListener('downloading', function(event) {
console.log("Started Download.");
}, false);
appCache.addEventListener('progress', function(event) {
console.log(event.loaded + " of " + event.total + " downloaded.");
}, false);
appCache.addEventListener('cached', function(event) {
console.log("Cached assets -- Done.");
}, false);
appCache.addEventListener('updateready', function() {
console.log("New resources are available for download -- update ready");
}, false);
appCache.addEventListener('obsolete', function(event) {
console.log("Obsolete - no resources are cached, and previous cache(s) are now deleted.");
}, false);
