Safari and iOS Private browsing

[mkraynov]

When I'm using Safari in Private Browsing, I got error: "An attempt was made to add something to storage that exceeded the quota."
Stackoverflow says it is by design of Private Browsing.

Can you set the cache to BasicCacheStorage instead of LocalStorageCacheStorage in this case? For example, borrowing the isLocalStorageNameSupported method from that StackOverlow link, you could do something like this:

var store;
if (isLocalStorageNameSupported()) {
  store = new Cache.LocalStorageCacheStorage();
} else {
  store = new Cache.BasicCacheStorage();
}
var cache = new Cache(-1, false, store);

@monsur can this detecting logic be absorbed into Cache's constructor so that the user won't worry about choosing storage?
