But based on the description you provided earlier about reduced SSL certificate management what you are doing isn't so much load balancing as SSL offloading. That means your load balancer must operating at OSI layer 7. > If so, when a user access's a CFM template does the IP of the person come > through properly as a CGI variable? If I use TCP load balancing (OSI layer 3) the IP address isn't changed, if I use application aware load balancing (OSI layer 7) it is and I have to add an X-Forwarded-For header.

I'm informed that this is the default for the Cisco ACE - the NAT automatically does the job of translating the client address through the VIP.

Re: ColdFusion Server behind a Citrix NetScaler (Load Balancer) CGI Issues
Jim, Most load balancers will set a HTTP header called "X-Forwarded-For" with the actual IP. We just created a request variable and used it in our apps. Here is the code we use just in case X-Forwarded-For doesn't exist. J.J.

I'll check with the network people - I have to check on the status of one of these ACE configs with them anyway.

Re: ColdFusion Server behind a Citrix NetScaler (Load Balancer) CGI Issues
Yes - our servers are behind a Cisco ACE and they show the correct remote address for CGI.REMOTE_ADDR and CGI.REMOTE_HOST.

Re: ColdFusion Server behind a Citrix NetScaler (Load Balancer) CGI Issues
Hello All, Does anyone operate a CF server behind a load balancer here? If so, when a user access's a CFM template does the IP of the person come through properly as a CGI variable? We are using a Citrix NetScaler and the CGI variable that always returns for a IP is that of the load balancer. We can weak the header file but that doesnât change the CGI variable for IP address coming back to ColdFusion.

RE: ColdFusion Server behind a Citrix NetScaler (Load Balancer) CGI Issues
Hi, On our load balancer (Coyote Equalizer) we have a setting, spoof, that forwards the client address to the web server instead of the load balancer address. Might be something similar on the Citrix box.
