Sending Last-Modified: should be easy; sending ETag needs some consensus
on the contents: mainly about validation. Responding to If-Modified-Since:
and If-None-Match: should cut at least _some_ of the page generating time.
If ETag can be calculated on URL alone, then we can cut If-None-Match:
just at beginning of script.

Indeed. Let me add myself to the pileup agreeing that a combination of
setting Last-Modified and checking for If-Modified-Since for
ref-centric pages (log, shortlog, RSS, and summary) is the smartest
scheme. I got locked into thinking ETags.

Sometimes it is easier to use ETags, sometimes it is easier to use
Last-Modified:. Usually you can check ETag earlier (after calling
git-rev-list) than Last-Modified (after parsing first commit). But
some pages doesn't have natural ETag...

Besides, because ETag is HTTP/1.1 we should provide and validate
both.

P.S. Any hints to how to do this with CGI Perl module?
