  • Re: ISAPI and IIS 10 Logging Issues

    Sep 06, 2017 08:03 PM|Miket03|LINK


    Here is a log Excerpt:

    #Software: Microsoft Internet Information Services 10.0
    #Version: 1.0
    #Date: 2017-07-02 00:00:00
    #Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs-version cs(User-Agent) cs(Referer) cs-host sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken
    2017-07-02 00:00:00 XX.X.X.XX GET /jakarta/isapi_redirect.dll - 443 - XX.X.X.XX HTTP/1.1

    As you can see in the log, the columns are correct but the actual cs-uri-stem and cs-uri-query are not logged properly.  It is only listing the ISAPI module that is called and not the page that was requested.

    I read about this happening with "IIS Advanced Logging" feature here: https://forums.iis.net/p/1168716/2134036.aspx?Re+IIS+Advanced+Logging+issues+with+Tomcat+and+web+application

    Do you know if IIS 10 incorporated specific changes in the logging of requests?  Perhaps any updates as to how it handles ISAPI filters in general?  It "feels" like IIS 10 incorporated the Advanced Logging features directly into the platform along with this bug.
