Thanks Max. I was just thinking of caching the iUI framework and a simple login page index. The rest of the site would not be cached but load external ajax links. Thus providing much faster load times for app with only html fragments being transferred. Could you provide a link to the html5 spec you mentioned. I have looked on google briefly, but only find small brief tutorials. I would like to look at something official.
