If using CloudSolrClient or another zookeeper aware client, then a request gets sent to Zookeeper to determine the live nodes. If indexing, CloudSolrClient can find the leader and send documents directly there. The client then uses that information to query the correct nodes directly.
Zookeeper is not forwarding requests to Solr. The client requests from Zookeeper and then the client uses that information to query Solr directly.
