+/**
+ * LBHttpSolrClient or "LoadBalanced HttpSolrClient" is a load balancing wrapper around
+ * {@link HttpSolrClient}. This is useful when you
+ * have multiple Solr servers and the requests need to be Load Balanced among them.
+ *
+ * Do <b>NOT</b> use this class for indexing in master/slave scenarios since documents must be sent to the
+ * correct master; no inter-node routing is done.
+ *
+ * In SolrCloud (leader/replica) scenarios, it is usually better to use
+ * {@link CloudSolrClient}, but this class may be used
+ * for updates because the server will forward them to the appropriate leader.
+ *
+ * <p>
+ * It offers automatic failover when a server goes down and it detects when the server comes back up.
+ * <p>
+ * Load balancing is done using a simple round-robin on the list of servers.
+ * <p>
+ * If a request to a server fails by an IOException due to a connection timeout or read timeout then the host is taken
+ * off the list of live servers and moved to a 'dead server list' and the request is resent to the next live server.
+ * This process is continued till it tries all the live servers. If at least one server is alive, the request succeeds,
+ * and if not it fails.
+ * <blockquote><pre>
+ * SolrClient lbHttpSolrClient = new LBHttpSolrClient("http://host1:8080/solr/", "http://host2:8080/solr", "http://host2:8080/solr");
+ * //or if you wish to pass the HttpClient do as follows
+ * httpClient httpClient = new HttpClient();
+ * SolrClient lbHttpSolrClient = new LBHttpSolrClient(httpClient, "http://host1:8080/solr/", "http://host2:8080/solr", "http://host2:8080/solr");
+ * </pre></blockquote>
+ * This detects if a dead server comes alive automatically. The check is done in fixed intervals in a dedicated thread.
+ * This interval can be set using {@link #setAliveCheckInterval} , the default is set to one minute.
+ * <p>
+ * <b>When to use this?</b><br> This can be used as a software load balancer when you do not wish to setup an external
+ * load balancer. Alternatives to this code are to use
+ * a dedicated hardware load balancer or using Apache httpd with mod_proxy_balancer as a load balancer. See <a
+ * href="http://en.wikipedia.org/wiki/Load_balancing_(computing)">Load balancing on Wikipedia</a>
+ *
+ * @since solr 1.4
