+Package nodes provides information and interaction with the Session Persistence
+feature of the Rackspace Cloud Load Balancer service.
+
+Session persistence is a feature of the load balancing service that forces
+multiple requests from clients (of the same protocol) to be directed to the
+same node. This is common with many web applications that do not inherently
+share application state between back-end servers.
+
+There are two modes to choose from: HTTP_COOKIE and SOURCE_IP. You can only set
+one of the session persistence modes on a load balancer, and it can only
+support one protocol. If you set HTTP_COOKIE mode for an HTTP load balancer, it
+supports session persistence for HTTP requests only. Likewise, if you set
+SOURCE_IP mode for an HTTPS load balancer, it supports session persistence for
+only HTTPS requests.
+
+To support session persistence for both HTTP and HTTPS requests concurrently,
+choose one of the following options:
+
+- Use two load balancers, one configured for session persistence for HTTP
+requests and the other configured for session persistence for HTTPS requests.
+That way, the load balancers support session persistence for both HTTP and
+HTTPS requests concurrently, with each load balancer supporting one of the
+protocols.
+
+- Use one load balancer, configure it for session persistence for HTTP requests,
+and then enable SSL termination for that load balancer. The load balancer
+supports session persistence for both HTTP and HTTPS requests concurrently.
