the real problem is
if u, instead, do
2. update a.jpg with other content.
your browser get a corrupted image. and it's "nicely" cached in client.
4. F5 (not ctrl+F5), re-request, got "not modified". too bad, the client will still see a big red cross X, most user don't know what there is CTRL+F5
particularly, i was checking lighttpd.rrd+images from lighttpd+browser.
