HTML5 cache size?

Question

I am creating a Web or iPad application that will use HTML5. After some research, I found that HTML5 has database caching and wonders how big this cache is?

I would like to provide a standalone solution so that users can fill out forms and extract information from the database if they are out of the field and cannot receive a 3G signal. Database caching would be quite large (a couple of tables with thousands of records each) and it would be re-cached weekly.

Is there a limit on the amount of data that HTML5 can cache?

Answer 1

I could not find anything about a hard limit on the size or any indication of the size limit when looking for any HTML documentation.

I believe Safari has a 5 MB limit for storing apps for iPhone / iPad (you mentioned using iPad.)

Here is the HTML standard regarding standalone web application / caching

Here's a good link related to implementing a standalone cache with HTML5 - it also has some good links at the bottom.

Hope this helps you!
