SYNOPSIS

         builder {
             enable "ConditionalGET";
             ....
         };

DESCRIPTION

       This middleware enables conditional GET and HEAD using "If-None-Match" and
       "If-Modified-Since" header. The application should set either or both of "Last-Modified"
       or "ETag" response headers per RFC 2616. When either of the conditions is met, the
       response body is set to be zero length and the status is set to 304 Not Modified.
