Does Opera realy supports picture(.gif,.jpg) and javascript(.js) file caching?

We are developing a web page for Nokia N800 with ajax that uses a lot of (40-100kb) of javascript that somehow is not cached in tablet PC Opera browser and each time i load the page all those files are loading and this increases page load-up time specially when using GPRS. Can i somehow solve this problem?


I also used opera:cache page to see cached files and unfortunately i could not see any!


Thanks for your future reply..
