🦿 Lucian Marin Fixed the ConditionalGetMiddleware in Django (github.com/django/...), but I think Sublevel will be better off without it. Calculating ETags for each request will consume too much CPU. Returning 304 code tells the browser not to re-render the page, but you still have to wait for a longer response from the server. ETags seem to be broken in Firefox because of the weak validator.

Martijn I believe h5bp's server configuration files disable ETags as well, both for performance reasons and because they aren't necessary in combination with other caching settings such as Expire headers. Don't think anyone will really notice it if Sublevel turns them off.
