browser has javascript enabled/disabled - such as check it in jsp etc

就可以知道了,用AUTO-REFRESH可以让用户觉得就一次REQUEST.

can probably do it in the first request. Just have a piece of javascript
setting an image url. If this image url is requested, the javascript
worked, otherwise not.
That said, I don't see much the server side can do with the first
request even after it has determined the client javascript availability.

Yes, but you don't need to refresh the whole page. That's what counts -
from a user experience standpoint, at least.
