Session-Aware Load Balancing

When you enable this feature, the ClusterCATS software load balances a Web server by redirecting users to another Web server before the user has established a new session. Once a user has started a session by typing in a URL or using an existing bookmark, ClusterCATS will not redirect the request. This feature is an alternative to the "Do not redirect" feature.

Note

This feature can be defeated by using absolute links in a page. By doing so, the HTTP request is routed back to the cluster entry point and redirected according to the current load threshold and without regard to the state of the requesting client. To avoid this inadvertent loss of state, be sure to use only relative linking in your application pages.

To set up session aware load balancing:

  1. In the ClusterCATS Explorer Main window, right click on the cluster where you want session-aware load balancing enabled. Select Configure > Administration. The cluster properties dialog box displays.
  2. On the Administration tab, click on the, Enable session-aware load balancing box to enable this feature.
