Just curious about ways to maybe save bandwidth for little mediawiki
installations as well as wikipedia:
Have the logos at the bottom of the screen, background images use the
central wikimedia ones ("hotlinked") instead of the ones that come
from the distribution .tar. And on the central wikimedia ones, have
Expires: Jan 1 2036 etc. HTTP header. Result: one copy cached forever
on the whole Internet? If one day regret Expires 2036, then just
change the filename when needed. Or maybe expires 1 year form now,
etc.
Maybe also somewhat for .css.
