The situation:
I'm using Varnish in front of some heavy loaded mod-php apache servers. When a cold (empty xcache, cold template cache) apache gets started, the server may overload because of too many requests.
The question:
Is there any way to have something like slow-start from nginx (http://nginx.org/en/docs/http/ngx_http_upstream_module.html#upstream , 'slow_start=time') for varnish ?
