When you create a namespace, the read-from-remote-system option and the option to service HTTP requests redirected from other HCP systems are both enabled, and the collision handling option is set to move objects. While the namespace is selected for replication, you can change these settings at any time. If the namespace is not selected for replication, these settings are hidden.
You may want to disable the option to service redirected requests if your applications cannot tolerate stale data or metadata. One way you could get stale data would be to request an object for which two versions exist but for which the current version hasn’t been replicated yet. In this case, you would get the old version from another system in the replication topology.

oTo allow or disallow HTTP requests that target the namespace to be redirected from other systems, select or deselect the Accept requests redirected from other systems in the replication topology option, respectively.
oTo change the collision handling option, click on Collision Handling. Then, in the Collision Handling section:
–To have HCP move objects flagged as replication collisions to the .lost+found directory, select the Move object to the .lost+found directory option.
–To have HCP rename objects flagged as replication collisions, select the Rename object and store in the same location option.

If you deselected the Enable replication option and this action may result in inaccessible object data, a confirming message appears.
In the window with the confirming message, select I understand to confirm that you understand the consequences of your action. Then click on the Update Settings button.
