The clusterDisableServer Web API Method

This method disables a cluster member. This process may be asynchronous if Session Clustering is used. If this is the case, the initial operation returns an HTTP 202 response. As long as the server is not fully disabled, further calls to this method are idempotent. On a Zend Server with no valid license, this operation fails.
