PIPE asserts

[Václav Bílek]

i redefined vcl_recv this way:

    if (req.request != "GET" &&
      req.request != "HEAD" &&
      req.request != "PUT" &&
      req.request != "POST" &&
      req.request != "TRACE" &&
      req.request != "OPTIONS" &&
      req.request != "DELETE") {
        /* Non-RFC2616 or CONNECT which is weird. */
        return (error);
    }

and get assert like this:

varnishd[7432]: Child (26652) Panic message: Assert error in
http_StatusMessage(), cache_http.c line 111:#012  Condition(status >=
100 && status <= 999) not true.  errno = 104 (Connection reset by peer)

= 0,#012    store = {#012    },#012  },#012},#012


is there any way how to block such bad request?
