I am running trunk now and the behavior is the same.

here is my complete vcl.conf (actual domain name changed.  let me know 
if you need to see it and i will send the file privately)

backend default {
     .host = "originserver.com";
     .port = "80";
}

sub vcl_recv {
     set req.url = regsub(req.url, "^", "/site");
     set req.http.X-Orig-Host = req.http.host;
     set req.http.host = "originserver.com";

     if (req.request == "POST") {
         pipe;
     }

     # force lookup even when cookies are present
     if (req.request == "GET" && req.http.cookie) {
         lookup;
     }
}

sub vcl_fetch {
     # force minimum ttl of 180 seconds
     if (obj.ttl < 180s) {
         set obj.ttl = 180s;
     }
}
