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?

Hi all, I'm asking around the traps on a question which has come up at work.

We want to develop an iPad app to will allow users to download from a

Is the offline storage tool in HTML5 designed for this sort of heavy lifting?
are there storage limitations?
on an iPad?

I've found a few examples of the tool in action and read bits and
pieces, but it all seems to be about storing small chunks of data, not
humunguous great whumps of it.

Apps are heavily sandboxed and there is no user accessible global file system.

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

2010-08-09 Thread Jody Tate
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.

Can you confirm, are you referring to Web Storage[1] or Offline 
Resources[2]?  Web Storage is really just cookies on steroids and 
probably isn't what you're after to store large amounts of binary data. 
 Offline Resources may be up to it, it's not clear to me what the 
limits are and I can't find any definitive documentation anywhere, but 
it's a whole different approach[3].
