ACE 4710 and Cookie problem

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.

Re: ACE 4710 and Cookie problem

You can get rid of nat - which would require a redesign (use policy routing or make ACE default gateway for servers).

If redesign is not possible, than you have to live with NAT.

ACE offers the http header insert function.

You could add the src ip of the client inside the http header.

Up to the server to retrieve the info and build whatever is needed.

If I have to live with NAT, how can I use http header insert function? Are there documentations related to this? I currently have A1(8.0) on the ACE. Thank you.
