If last-modifed date of file is not changed, bandwidth saved:

and if time in request same as time of file modification on disk nginx send reply HTTP/1.x 304 Not Modified

In general Etag for static files is not better than Last-Modified header.

Etag is useful for dynamic content, when modify time is not known. In this case Etage can be generated from hash (md5/sha) of content.

Can this work with the memcached module in any way? For instance, if the resource requested is in the memcached store then the 304 header is sent?
