Comment:

 Transfer-Encoding: chunked is a very special header, that affects how the
 body of the object is transmitted on the wire.

 It is not a header you should ever set from a CGI script, and if you do,
 your webserver should detect it and handle it properly, either by removing
 it again or by switching to chunked transmission mode.

 Varnish does the right thing in this case, because the HTTP response it
 receives makes no sense.
