The zero ESI change is now live, but is enabled only when X-FORCE-ESI header is set to "1". Also, it won't work until varnish enables ESI support for zero requests (see doc<https://www.varnish-cache.org/docs/3.0/tutorial/esi.html> )
I propose the following deployment steps: 1) set beresp.do_esi = true for all requests with X-CS header. (should not be enabled for javascript or any other non-html resources) This will let us measure ESI impact when HTML has no <esi:include> tag. 2) Enable X-FORCE-ESI header for one or more smaller carriers while monitoring the impact on varnish load 3) Enable ESI configuration flag for all zero partners 4) Remove cache variance on X-CS header On Tue, Jun 18, 2013 at 12:06 PM, Yuri Astrakhan <yastrak...@wikimedia.org>wrote: > Hi Mark, > > On Tue, Jun 18, 2013 at 11:58 AM, Mark Bergsma <m...@wikimedia.org> wrote: > >> > >> > * All non-local links always point to a redirector.
