    I've been developing an ISAPI filter and have ran into what I believe is a bug with IIS 7 and 8

    In the SF_NOTIFY_LOG event the HTTP_FILTER_LOG has 4 params that are virtually always incorrect. 

       DWORD dwWin32Status;
   DWORD dwBytesSent;
   DWORD dwBytesRecvd;
   DWORD msTimeForProcessing;
    dwWin32Status rarely matches what is places in the log for non zero events. (i.e. will return 0 or 995, yet the log will show 64)
    dwBytesSent is always 0
    dwBytesRecvd is always 0
    msTimeForProcessing is always 0
    All other params of the structure are always correct. 
    Is there a fix or work around for this?
    (Sorry if this is the wrong forum, was unable to find anything specific to IIS)

    Hi，

    Thanks for posting here.

    As far as I know, in IIS 7, it seems it is a known issue. Please refer to the link below.

    IIS 7 ISAPI filter – dwBytesRecvd & dwBytesSent in HTTP_FILTER_LOG struct are always 0 [Answered]

    However, whether the issue is still in IIS 8, I suggest you confirm from IIS related forum for a better support. The proper forum will be here http://forums.iis.net/default.aspx/41?IIS+7+and+Above. Because I can not help you move this case from MSDN to IIS, you need to post a new thread for this issue, sorry about this inconvenience.

    Best Regards,

    May
