I'm not sure I quite understand you here. Perhaps you could give a 
more concrete example? Most shopping cart apps I'm aware of are very 
dynamic and customize heavily per user and per page. Otherwise how 
could you show the user what's in their basket? So I don't think 
you'd want to cache this at all, with or without cookies, but maybe 
I'm missing something?
