+1. For reference see http://httpd.apache.org/docs/2.2/en/mod/mod_cache.html#cachelastmodifiedfactor. I may be off track here since we have no cache here, but it may be a good idea to add a Warning header with a Warning 113 in the cases described in RFC 2616 14.46 (see also 13.2.2 and 13.2.4) as we would have a heuristic expiration time here.
