 Varnish return no content when a query use HTTP/1.0 and the backend don't
 send a content-header.

 Log sample :

 {{{
 15 TxRequest    b GET
 15 TxURL        b /bug.php
 15 TxProtocol   b HTTP/1.0
 ...
 15 RxProtocol   b HTTP/1.1
 15 RxStatus     b 200
 15 RxResponse   b OK
 15 RxHeader     b Date: Fri, 11 Jan 2008 14:32:33 GMT
 15 RxHeader     b Server: Microsoft-IIS/4.0

 }}}

 this can be solved by patching /bin/varnishd/cache_fetch.c :

 {{{

                 VSL(SLT_Debug, vc->fd, "Invalid Transfer-Encoding");

                 return (-1);
 -       } else if (strcmp(http_GetProto(hp), "HTTP/1.1")) {
 +       } else if ((strcmp(http_GetProto(hp), "HTTP/1.1")) ||
 (strcmp(http_GetProto(hp), "HTTP/1.0"))) {
                 switch (http_GetStatus(hp)) {
                         case 200:
                                 cls = fetch_eof(sp, vc->fd, hp);
