css - Data-URI's and caching -

-

i read this on wikipedia:

data uris not separately cached containing documents (e.g. css or html files) data downloaded every time containing documents redownloaded.

does mean code downloaded every single time page refreshed or whenever user clicks on navigation link? can cache data-uri's?

ps - i'm talking 20 or small png files (mostly silk icons 2 * 16kb files well)

data uris nothing more text in form of base64-encoded binary data, that's embedded within html , css files. yes, downloaded part of html , css files every time they're requested, unless files cached.

if keep data uris stylesheets , send proper cache headers, caching data: images css shouldn't pose issues.
