varnishd -C

[I I]

yeah.I had set this. So I found some url not marked by the varnish .and
there urls request to backend server .
although I find that the pipe mode will not mark any to the HEADERS.but if
the urls process by the pipe, there will be log in the varnishlog.
unfortunately ,I can't find any about there urls in the varnishlog.
