|Try to limit HTML pages to 25.6KB or less if you want them to be cached, since the previous tests showed that this limit—imposed by iOS 3.2 on the iPad—was the lowest HTML resource limit of the devices tested.
|Keep CSS and JS components under 1MB. Of course, 1MB is enormous and your components should be much smaller than this, but don’t bother splitting a component into separate requests for the sake of cacheability unless its size approaches 1MB.
|Consider using the HTML5 application cache if it’s important that your components persist in the cache for a long time, or across power cycles.''
