Is there any existing module that is enable to automatically account for fields definition in the W3C logs? If not, would it be possible to consider developping one? I know there already is an IIS module but it is based on a standard field order / presence but it definetly lacks flexibility. If the answer to both question is no, has anyway found a workaround? I was thinking of maybe using LogParser2 with a powershell script to directly pus to the stack but I don't like the _homemade_ sound of it. ---

If there is no module that natively supports the W3C format, where can I log a feature request? Also, has anyone came up with a custom tools solution that could fulfill this requirement? ---
