On further inspection of source and tickets, using "pipe" and
'req.http.connection = "close";' should be done for 1.1.2.  For 1.2,
which includes the "2115" changeset, you should be able to use "pass"
instead of "pipe" for POST, enabling connection reuse.

My relevant vcl for 1.2 :

sub vcl_recv {

  # Normalize Host: header to limit cache usage
  if (req.http.host ~ "^(www.)?fnord.no") {
    set req.http.host = "fnord.no";
    set req.backend   = zope_195;
    set req.url       = "/VirtualHostBase/http/fnord.no:80/Sites/fnord.no/VirtualHostRoot" req.url;
  } elsif (<another site>) {
    # [...]
  } else {
    error 404 "Unknown virtual host"
  }

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

  if (req.request != "GET" && req.request != "HEAD") {
    # [...]
  }

  # [...]
}


A few short tests on one of my own sites shows it to not break
immediately, at least. :)
