  • 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:
    sdraw-w3c.exe <log-date> <raw-log-file> <w3c-log-file>
    Raw request log files are enabled in the Simple DNS Plus Options dialog / Logging / Log Files section.
    The zip file below contains both the compiled .exe file as well as the C# source code (VS2008). This is a very simple program so if you want to add some type of filtering (only output some requests) or build on this functionality, it is easy to do so.

  • Simple DNS Plus API for .NET and COM (Deprecated)
    For details see the included help file, also available on-line.
    Click here to download "sdnsapi-setup.exe" (720 KB)
    NOTE: This library is deprecated and is no longer maintained. It still works, also with the current version of Simple DNS Plus, but it does not support all new features and record types added in recent versions of Simple DNS Plus. We recommend using the HTTP API directly instead.
    NOTE: This library always authenticates with the the user-ID "admin" as this was fixed in earlier versions of Simple DNS Plus. So for recent versions of Simple DNS Plus where to HTTP API user-ID is configurable, you need to set this to "admin".
