  • Re: ISAPI and IIS 10 Logging Issues

    Nov 17, 2017 06:57 PM|lextm|LINK


    I finally managed to figure out what the issue is/was.  The c:\windows\system32\inetsrv\config\applicationHost.config file has a definition for IsapiFilter in the <location path="" overrideMode="Allow"><system.webServer><modules> section.  The IsapiFilterModule needs to be before the HttpLoggingModule in the list.  I've made this change on all of my Windows 2016 servers where logging wasn't working and they're all happy now, logging correctly.

    You should mark that as an answer. Great that you locate the culprit.

    In the meantime, Microsoft itself created HttpPlatformHandler to integrate with web technologies such as Java and Go, you should be free of any third party ISAPI right now.
