Cache strategy

Cache strategy

Getting cached most elements of a mobile web app/page is obviously important... right?
 
Some time ago, when the first version of iphone was the only true "smart phone" I was trying to use jquery-core on a web app but discovered that mobile browser did not cache files over 21~27 kb. Someone known if this limitation is still there on modern phones?

This jQuery mobile looks amazing!, Writing js without jQuery is no fun!
