What I was driving at was if you list in a 'parent' manifest five pages, and each of those pages have manifests, does the browser download all files in those five manifest files?

Re: [WSG] HTML5 offline storage question
I've played around with the appCache quite a bit and it certainly has its limitations. If you make an update to the manifest file it will re-download every asset listed in the manifest. The limit, although it isn't documented anywhere, is 5mb for iPhone and 10mb for iPad. It's really only designed for assets that will rarely change.

Re: [WSG] HTML5 offline storage question
You can store on iPhone with Web Database any amount of data. It will just ask user does he really want to allow this site to use, say, 100mb. My application for the iPhone stores 150mb now.

Re: [WSG] HTML5 offline storage question
Asking why not just use the cache is a valid question. In this case, using HTML5 storage to house files doesn't seem to be tapping into all HTML5 storage can do--but it's not violating what storage can do either (so far as I know). HTML5 storage is like cookies: Simply put, it’s a way for web pages to store named key/value pairs locally, within the client web browser. Like cookies, this data persists even after you navigate away from the web site, close your browser tab, exit your browser, or what have you. Unlike cookies, this data is never transmitted to the remote web server (unless you go out of your way to send it manually). That's from: http://diveintohtml5.org/storage.html#localstorage So, HTML5 storage is more for data storage--storing key/value pairs (like massive cookies)--than just a repository of files. This is how I understand it. Others may know more. I'd think a iPhone/iPad native app would want to look beyond HTML5 storage and into File Management. But if this is a web app, then HTML5 storage might be the only option. But I'm far from being an expert. -jody On Aug 9, 2010, at 12:59 AM, Josh Godsiff wrote: I avoid Apple products like the plague, so perhaps I'm missing some info here, but what's wrong with simply getting the user to download the file in the normal fashion? - Josh On 9/8/2010 3:11 PM, Breton Slivka wrote: The iPhone has a 5mb upper limit per page.
