Issue always seems to be pulling comments for each page load. Loading comments with a GET, with a ttl > 0 seems to work well for us (no ESI). Is there a reason you are running with TTL at zero? Yeah, sorry, it was not so much about the TTL as the ability to still lookup the cached page and pass the POST through to the ESI. I understand we can increase the TTL of the ESI, but the real goal here is to have a separate ESI only server that handles all authenticated traffic, while keeping the frontend server served completely from the Varnish cache. Ah yes. Consider a subdomain. We pipe for cases like this. Can you describe a bit more what you mean? We have our frontend site, origin.example.com, which has ESIs pointing to ugc.example.com (ugc == user generated content). If you pipe in vcl_recv, ESIs are not processed. Maybe I'm missing something. :) Indeed, I'm not using ESI, but if I need varnish to handle something I pass.
