W3C Extended Log File Format (IIS 6.0)

W3C Extended Log File Format (IIS 6.0)

The W3C Extended log file format is the default log file format for IIS. It is a customizable ASCII text-based format. You can use IIS Manager to select which fields to include in the log file, which allows you to keep log files as small as possible. Because HTTP.sys handles the W3C Extended log file format, this format records HTTP.sys kernel-mode cache hits.

Table 10.1 lists and describes the available fields. Default fields are noted.
