  • Convert Simple DNS Plus logs to W3C Extended log format
    Use Simple DNS Plus raw request log files (.sdraw) with tools, such as log web-site traffic analyzers, that understand the standard W3C Extended format (as typically produced by IIS, Apache, and other web-servers).
    The command line syntax is:

    Raw request log files are enabled in the Simple DNS Plus Options dialog / Logging / Log Files section.
