1.  Introduction

   This memo defines a set of objects for managing World Wide Web (WWW)
   services. This MIB extends the application management framework
   defined by the System Application Management MIB (SYSAPPL-MIB) [23]
   and the Application Management MIB (APPLICATION-MIB) [24]. The MIB is
   also self-contained so that it can be implemented and used without
   having to implement or install the APPLICATION-MIB or the SYSAPPL-
   MIB.

   The protocol statistics defined in the WWW Service MIB are based on
   an abstract document transfer protocol (DTP). This memo also defines
   a mapping of the abstract DTP to HTTP and FTP.  Additional mappings
   may be defined in the future in order to use this MIB with other
   document transfer protocols. It is anticipated that such future
   mappings will be defined in separate RFCs.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [17].

2.  The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

    o   An overall architecture, described in RFC 2571 [1].

    o   Mechanisms for describing and naming objects and events for the
        purpose of management. The first version of this Structure of
        Management Information (SMI) is called SMIv1 and described in
        STD 16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The
        second version, called SMIv2, is described in STD 58, RFC 2578
        [5], RFC 2579 [6] and RFC 2580 [7].

    o   Message protocols for transferring management information. The
        first version of the SNMP message protocol is called SNMPv1 and
        described in STD 15, RFC 1157 [8]. A second version of the SNMP
        message protocol, which is not an Internet standards track
        protocol, is called SNMPv2c and described in RFC 1901 [9] and
