HTTP_LOGGING_TYPE enumeration

The HTTP_LOGGING_TYPE enumeration defines the type of logging that is performed.

This enumeration is used in the HTTP_LOGGING_INFO structure.

Syntax

typedef enum _HTTP_LOGGING_TYPE {
  HttpLoggingTypeW3C,
  HttpLoggingTypeIIS,
  HttpLoggingTypeNCSA,
  HttpLoggingTypeRaw
} HTTP_LOGGING_TYPE, *PHTTP_LOGGING_TYPE;

Constants

HttpLoggingTypeW3C The log format is W3C style extended logging. Applications choose the fields that are logged in the Fields member of the HTTP_LOGGING_INFO structure.

When this type of logging is set on a URL Group, logging is similar to the IIS6 site logging. When set on a server session this format functions as a centralized logging for all of the URL Groups.
HttpLoggingTypeIIS The log format is IIS5/6 style logging. This format has a fixed field definition; applications cannot choose which fields are logged. This format cannot be chosen when setting the logging property on a server session.
HttpLoggingTypeNCSA The log format is NCSA style logging. This format has a fixed field definition; applications cannot choose which fields are logged. This format cannot be chosen when setting the logging property on a server session.
HttpLoggingTypeRaw The log format is centralized binary logging. This format has a fixed field definition; applications cannot choose which fields are logged. This format cannot be chosen when setting the logging property on a URL Group.
