HTTP_FILTER_ACCESS_DENIED Structure

IIS includes a pointer to this structure when a user is presented with an Access Denied error message. If your filter should be notified for this event, it should register for the SF_NOTIFY_ACCESS_DENIED event.

typedef struct _HTTP_FILTER_ACCESS_DENIED HTTP_FILTER_ACCESS_DENIED {
      const CHAR * pszURL;
      const CHAR * pszPhysicalPath;
      DWORD dwReason;
} HTTP_FILTER_ACCESS_DENIED, * PHTTP_FILTER_ACCESS_DENIED;

Members

  • pszURL
    Points to a null-terminated string that specifies the URL that requested access to the resource.

  • pszPhysicalPath
    The physical path of the resource that was requested.

  • dwReason
    A DWORD containing flags that indicate the reasons for the denial. Can be one of the following values.

    Value

    Meaning

    SF_DENIED_LOGON

    The client could not be logged on.

    SF_DENIED_RESOURCE

    A Windows DACL denied the resource.

    SF_DENIED_FILTER

    An ISAPI filter denied the request.

    SF_DENIED_APPLICATION

    An ISAPI extension or CGI application denied the request.

    SF_DENIED_BY_CONFIG

    The server configuration denied the request. For example, disabling anonymous requests on the server would generate this filter notification when a user without credentials tried to make a request to the server.

Remarks

This structure indicates that the server has denied access to the requested resource. The structure is generated when there has been a logon failure, or if a user requests a resource that has an associated discretionary access control list that does not include the logged-on user.

The server will automatically include the supported authentication schemes when an ISAPI extension, filter, or CGI script returns a 401 Access Denied error code.
