I found this in my log today -- what are ETags?

See RFC 2616 (HTTP/1.1).
ETag is an unique object identifier identifying an exact version of an URL. Exists in both strong (guaranteed unique) and weak (possibly not unique) variants. For certain queries such as If-Range only strong ones is acceptable to prevent that partial content from two difference versions of the URL gets merged.
