static.File supports If-Modified-Since and Last-Modified:
Try running:
$ curl -H'If-Modified-Since: Mon, 28 Mar 2005 04:58:37 GMT' -i  
'http://twistedmatrix.com/'
and notice how it returns a 304 Not Modified.

Cache-Control and Expires are not relevant to a static file resource. 
But yes, it's not returning an ETag.
