Client IP Preservation without ISAPI filter

Hi,

 

Where a VIP has SNAT enabled, is there any way to log the original client IP address in a back end IIS server without having to install an ISAPI filter?

    The X-Forwarded-For header value is accessible using CGI variables. So the application could get the XFF value(s). But I'm pretty sure that in order to have IIS log this value, you'd need to install an ISAPI DLL.
