So it seems reasonable to expect fcl-web to pass a default agent header.
( Quoting Remy Lebeau )
"The User-Agent header is optional in RFC 2616. It SHOULD be used by clients, but it is not REQUIRED to be used. All of the major third-party browsers/clients use it, but custom apps/APIs/bots/etc might not. There are webservers that alter responses, or even reject requests (which is annoying), based on the User-Agent provided (or lack of one)."
PLz, fill a feature request ... ( IMO it's not a bug ).
