TEST PROCEDURE

        This test sequence is following.
    DNS Client1 (NUT)                               DNS Server1 (TN)
        |                                               |
        | Invoke some application                       |
        |    on NUT (Ex. HTTP)                          |
        |                                               |
        |---------------------------------------------->|
        | 1. Send standard query                        |
        |    QNAME="http.uri.arpa."                     |
        |    QTYPE=NAPTR                                |  
        |                                               |
        |<----------------------------------------------|
        | 2. Send standard query response               |
        |                                               |

        | 3. Send standard query                        |
        |    QNAME="www.example.com"                    |

        1. DNS Client (NUT) sends a standard query with QNAME = "http.uri.arpa." type = NAPTR 
        2. DNS Server1 (NUT) transmits a response to DNS Client1 (NUT) with:
           $ORIGIN http.uri.arpa. 
           ;;       order pref flags service  regexp                       replacement
           IN NAPTR 100   90   ""    ""       "!^http://([^/:]+)!1!i"      .
        3. DNS Client (NUT) sends a standard query with QNAME = "www.example.com." type = NAPTR. Judgment (Check *3)
