To avoid grabbing lots of duplicates on sites like Tumblr blogs, we should be able to use existing WARC indexes (or something) to:

figure out what URLs existed in a previous snapshot,
if we see those URLs, figure out an appropriate ETag and/or Last-Modified,
send that ETag/Last-Modified,
write the 304 if we get one, 200 otherwise.
