Hi there,
I have a big problem concerning the XFF Data of my IIS 6.
Usually we used IIS 5 with a network card based Loadbalancing. This worked fine with logging the IP Adresses, that requested sites over the IIS.
After changing to IIS6 and a Hardware Loadbalancer that was set bevor the IIS 6 (there are two IIS6 webservers clustered, that are served with rewuests by the hardware LB), we had the problem that only the IP Adress of the Load Balancer appeared in the log files.
Therefore our LoadBalancer specialist set on XFF to send the IP Adresses to the IIS Webservers. But here is the problem. I found one application, that could be integrated in the IIS6 via ISAPI Filters ( its the Plug In from Winfrasoft).
My question now is:
Is there any other Application /ISAPI Plug In that could also serve XFF for Windows IIS 6 Servers? (Best would be an ISAPI that also provides XFF to IIS 5 - 7).
