These loosely follow the model set in [Google Cloud Policies](https://cloud.google.com/load-balancing/docs/ssl-policies-concepts). We [track changes](../security/tls_configuration_history.md) to this policy.

By default, OkHttp will attempt a `MODERN_TLS` connection.  However by configuring the client connectionSpecs you can allow a fall back to `COMPATIBLE_TLS` connection if the modern configuration fails.

  - Replication (Server Side Replication)

## Prerequisites

- It is assumed you have users created and configured with relevant access policies, to start with
  use basic "readwrite" canned policy to test all the operations before you finalize on what level
  of restrictions are needed for a user.

- No "admin:*" operations are needed for FTP/SFTP access to the bucket(s) and object(s), so you may

func (s *peerRESTServer) GetLocksHandler(_ *grid.MSS) (*localLockMap, *grid.RemoteErr) {
	res := globalLockServer.DupLockMap()
	return &res, nil
}

// DeletePolicyHandler - deletes a policy on the server.
func (s *peerRESTServer) DeletePolicyHandler(mss *grid.MSS) (np grid.NoPayload, nerr *grid.RemoteErr) {
	objAPI := newObjectLayerFn()
	if objAPI == nil {
		return np, grid.NewRemoteErr(errServerNotInitialized)

In OkHttp we expose a blocking API over a framed protocol. This document explains the code and policy that makes that work.
