Session Configuration
From CauchoWiki
Session configuration occurs in three contexts:
- In the web-app's <session-config>
- In the <server> cookie configuration
- In the persistent session configuration
The <server> block has a separate cookie configuration because the load-balancers need to detect and parse the session cookie on a server-wide basis to implement sticky sessions.
