With the help of a vmod
(https://github.com/KristianLyng/libvmod-header), you could add a
special cookie to the response and match it early in vcl_recv().

import header;

if (req.http.Cookie ~ "(^|; )VCLPIPE=1") {

if (req.url ~ "^/login") {
	header.append(beresp.http.Set-Cookie,"VCLPIPE=1; path=/");
