   * Session persistence is a feature of the load balancing service that forces 
   * multiple requests, of the same protocol, from clients 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. Two session persistence 
   * modes are available, as described in the following table:
   * 
   * * HTTP_COOKIE: A session persistence mechanism that inserts an HTTP cookie 
   *      and is used to determine the destination back-end node. This is supported 
   *      for HTTP load balancing only.
   * 
   * * SOURCE_IP: A session persistence mechanism that will keep track of the 
   *      source IP address that is mapped and is able to determine the destination 
   *      back-end node. This is supported for HTTPS pass-through and non-HTTP 
   *      load balancing only.
