Hi,

What is the ACE model, which you are using now and how did you configured sticky now on your device?

Example of IP Address Sticky Configuration

The following example illustrates a running configuration that defines IP address stickiness.The IP address stickiness configuration appears in bold in the example.

In this configuration, the ACE uses IP address stickiness to stick a client to the same server for multiple subsequent connections as needed to complete a transaction using the client source IP address, the destination IP address, or both.

It Depends on your scenario as well. But this type of sticky is the basic method get the sticky table created and worked out. you can restrict it only with source not with destination something like that you can do with this.
