Using ESI-tags inside a cached object

[Kasper Grubbe]

I am following the guide here:
https://www.varnish-cache.org/docs/trunk/tutorial/esi.html

I have two pages in my project as of now:

1. http://127.0.0.1:3001/ (Cache-Control:max-age=60, private):
<b>Cached:</b> <%= Time.now %> <br/>
<b>ESI:</b> <esi:include src="/staticview" /> <br/>

2. http://127.0.0.1:3001/staticview (Cache-Control:max-age=1, private):
<%= Time.now %>

However, every time I request the first page, it seems like it also
caches the ESI-include result for the 60 seconds instead of refreshing
every second.

First request:
Cached: 2012-07-09 01:31:12 +0200
ESI: 2012-07-09 01:31:12 +0200

Second request (10 seconds later):
Cached: 2012-07-09 01:31:12 +0200
ESI: 2012-07-09 01:31:12 +0200

Third request (about a minute later):
Cached: 2012-07-09 01:32:19 +0200
ESI: 2012-07-09 01:32:19 +0200

Is this expected? Or am I misunderstanding the documentation?

My VCL config looks like this:
backend default {
  .host = "127.0.0.1";
  .port = "3000";
}

sub vcl_recv {
  # Don't cache POST, PUT, or DELETE requests
  if (req.request == "POST" || req.request == "PUT" || req.request ==
"DELETE") {
    return(pass);
  }

  return(lookup);
}

sub vcl_fetch {
  # We want ESI
  set beresp.do_esi = true;

  if (beresp.http.Cache-Control ~ "max-age") {
     unset beresp.http.Set-Cookie;
     return(deliver);
  }

  # Do not deliver into cache otherwise.
  return(hit_for_pass);
}

sub vcl_deliver {
  if (obj.hits > 0) {
    set resp.http.X-Varnish-Cache = "HIT (" +obj.hits+ ")";
  } else {
    set resp.http.X-Varnish-Cache = "MISS";
  }
}

Varnish is running with these parameters:
varnishd -F -a 127.0.0.1:3001 -f config/varnish/development.vcl

My Varnish version is this (running on Mac OS X, with Varnish from the
Homebrew repo):
varnishd (varnish-3.0.2 revision 55e70a4)
