What is XFF? (X-Forwarded-For)
When web servers are placed behind the TR7 Load Balancer, the servers' log files will display the TR7 SNAT IP address. The XFF (X-Forwarded-For) HTTP header is used to forward the client IP address to the servers. On TR7 ASP, sending the XFF header to the servers can be easily configured as shown in the following step.
