clusterRemoveServer

This method removes a server from the cluster. The removal process may be asynchronous if Session Clustering is used. If this is the case, the initial operation will return an HTTP 202 response. As long as the server is not fully removed, further calls to remove the same server should be idempotent. On a Zend Server Cluster Manager with no valid license, this operation fails.

202 Accepted - The removal process has started but not completed yet. The user may want to check the server status within a few seconds using the clusterGetServerStatus method to verify that the operation was completed.
