Something outside the HTTP protool has been injected, So Squid will drop the header, if relaxed_header_parser is disabled then the whole response is dropped. In this case the reponse is: HTTP/1.1 204 No Content Server: nginx Content-Type: text/html Connection: close Date: Tue, 12 Nov 2013 08:29:00 GMT P3P: CP="CUR ADM OUR NOR STA NID" Set-Cookie: ljt_reader=9927a11290d0240d8b2c3a6526658585; expires=Wed, 12-Nov-2014 08:29:00 GMT; path=/; domain=.lijit.com :: Expires: Thu, 01 Jan 1970 00:00:01 GMT Cache-Control: private, no-cache, no-store, must-revalidate, max-age=0 Pragma: no-cache Notice the line which contains only "::".
