clusters is 600 seconds (10 Minutes). If your site is extremely busy, you might want to use a
shorter sticky time period.
By enabling inter-cluster stickiness, you can ensure that requests from a particular client are
directed to the same server even if the connection is to a different virtual cluster.
Inter-cluster stickiness must be enabled for all of the clusters that you want to bind
together. The clusters that have inter-cluster stickiness enabled should contain identical
sets of server IP addresses. For example:
Cluster www.coyotepoint.com:http
Server srv1
Server srv2
Cluster www.coyotepoint.com:https
Server srv1
Server srv2
To enable sticky connections:
1. Log into the Equalizer Administration interface with edit access.
2. In the left frame, click the name of the cluster you want to configure. The Cluster
Parameters are displayed in the right frame.
3. Select Change Cluster Parameters from the local menu in the Cluster Parameters
frame. The Change Cluster dialog is displayed in the right frame.

stickiness can only be turned on if sticky connections are enabled by specifying a
sticky time greater than zero.)
6. Click the Set button.
