Migrate from web container mode to standalone mode

Consider these points to migrate from IG in web container mode to IG in standalone mode.

Session replication between IG instances

High-availability of sessions is not supported .

Streaming asynchronous responses and events

In ClientHandler and ReverseProxyHandler, use only the default mode of asyncBehavior:non_streaming; responses are processed when the entity content is entirely available.

If the property is set to streaming, the setting is ignored.

Connection reuse when client certificates are used for authentication

In ClientHandler and ReverseProxyHandler, use only the default mode of stateTrackingEnabled:true; when a client certificate is used for authentication, connections cannot be reused.

If the property is set to false, the setting is ignored.
