Assuming that you have some way of calculating the '304 Not Modified', 
there is nothing in a CGI that precludes returning that result from a 
query string, but not from a Range header.  Unless you are suggesting 
that the web server can calculate 304 results even for a queried range, 
without the help of an RDF gateway?
