    Hello Steve.

    Try to downgrade your HTTP connection in order to avoid "Transfer-Encoding: chunked"

    when HTTP_REQUEST {
	HTTP::header remove "Accept-Encoding"
	if { [HTTP::version] eq "1.1" } {
		if { [HTTP::header is_keepalive] } {
			HTTP::header replace "Connection" "Keep-Alive"
		}
		HTTP::version "1.0"
	}
}

    Regards,

    Dario.
