What are the options to cache random data in a browser environment?

If I happen to retrieve a bunch of random data (text in my case), what are all the options for caching it across page loads?

Currently I can think of:

• localStorage
• indexedDb
• userData

Basically these are the key factors:

• As much storage as possible
• Store it for a day at least
• Can be done programmatically with JavaScript
• As high cross-browser开发者_如何学Go solution as possible

If you can afford to create this in HTML5 only, supporting only modern browsers, I would advice "Mark Pilgrim's DiveIntoHTML5 chapter on Web Storage". Since this is the only official standard, it has an advantage over custom browser-specific storage options.
