An Internet Information Services (IIS) Web server can be configured for Site, Central Binary, or Central W3C logging. In Central W3C logging, all client requests for all sites are logged to a single log file in W3C centralized format on the server. Central Binary logging also logs all sites centrally to a single file, but does so in centralized binary format. In Site logging, all client requests are logged at the site level, not centrally at the server level. These logging types depend on the World Wide Web Publishing Service for their configuration.
