	I've tried also to remove such header in vcl_fetch, as such header seemed not 
to be reachable in vcl_recv (varnishd told me when I tried):

sub vcl_fetch {
    if (obj.http.Content-length == "0") {
        remove obj.http.Content-length;
    }
    if (!obj.cacheable) {
...

	That's the only deviation apart from the usual trick for serving content 
without checking with backend:

#    if (req.http.Authorization || req.http.Cookie) {
    if (req.http.Authorization) {

from the shipped default.vcl file.

	Thanks in advance,
