4. Once the instances are stopped, click Start Instances.

Verifying HTTP Session Failover

The steps for testing session data failover are similar for testing load balancing as described in the topic “Verifying Load Balancing” on page 20. This time Session Data is preserved after failure. Failover is transparent to the user because the sample application is configured for automatic retry after failure.

To Verify HTTP Session Failover

Steps 1. To display the first page of the clusterjsp application, type this URL in your browser:

http://localhost:web_server_port/clusterjsp

Replace the localhost variable with the name of the system that the Web Server is running on.

Replace the web_server_port variable with the value of the port attribute of the LS element in web_server_install_dir/https-hostname/config/server.xml. For this example, port 38000 is used.

A page similar to what you saw in “To Verify the Application Deployment” on page 16 appears.

2.Examine the Session and Host information displayed. For example:

Executed From Server: localhost

Server Port Number: 38000

Executed Server IP Address: 192.18.145.133

Session ID: 41880f618e4593e14fb5d0ac434b1

Session Created: Wed Feb 23 15:23:18 PST 2005

3.View the server access log files to determine which application server instance is serving the application. The log files are located here:
