I plan to load balance user traffic to a server farm. Currently, server is using cookie to generate delay/response time statistic for users from various locations. If I use ACE to load balance user traffic, I need to use NAT statement on ACE to make the design to work. However, server can no longer use cookie to generate such statictics since source address is now a NATed address. Is there a way to rectify this problem? Thank you in advance.
