Does the HTML 5 application (offline) cache have any benefit for online/connected apps?

My page needs to be online to function and is loaded exclusively in a UIWebView as part of an iOS app. This page is loading some large dependencies and I was wondering if I could use the HTML 5 app cache to store these dependencies to avoid relying on the regular browser cache.

So I guess my question is:

When an HTML 5 page is online, does it use the offline cache if a dependency already exists in the HTML5 offline cache?

    Yes, the HTML5 offline application caching works with online applications, allowing you to benefit from indefinite local caching. For example, see http://www.w3.org/TR/html5/offline.html#concept-appcache-onlinewhitelist about the ability to specifically whitelist particular URLs which do not get cached.
