Description Krinkle 2012-07-04 17:22:45 UTC 
The last modified timestamp is available and already being included:

header( 'Cache-Control: s-maxage=3600, must-revalidate, max-age=0' );
header( "Last-modified: $lastmod" );

We could extend this further and make it respond with "304 Not Modified" (without body content) for requests that have the same version cached. Should save a fair amount of bandwidth.

Should it be added to the new hackathon's topics? :)
Comment 3 Krinkle 2014-10-06 09:55:40 UTC 
Seems http://www.wikipedia.org and similar hits are now actually yielding 304 Not Modified client-side. I suspect maybe the switch to Varnish made this happen at the abstraction layer there.
