IIS Extended W3C Log File Format
Microsoft Internet Information Server (IIS) Extended W3C log file format is an ASCII format which can use many fields. This format is defined by the World Wide Web Consortium.
eWebLog Analyzer requires the following fields:
- Date
- Time
- IP Address
- Method
- File Requested
- Status
- Client Bytes
The Agent and Referrer fields are optional, but highly recommended, as they provide information on where users are coming from and what browsers and operating systems they are using to access your web site.
