Deleting proxy array members will remove them from the proxy array. You can only delete proxy array members from the master proxy.
You should only make changes or additions to the proxy array member list through the master proxy in the array. If you modify this list from any other member of the array, all changes will be lost.
Access the Server Manager, and click the Caching tab.
Click the Configure Proxy Array link. The Configure Proxy Array page displays.
In the Member List, select the radio button next to the member that you want to delete.
Click the Delete button.
If you want your changes to take effect and to be distributed to the members of the proxy array, you need to update the Configuration ID on the Configure Proxy Array page and click OK. To update the configuration ID, you can simply increase it by one.
Click Restart Required. The Apply Changes page displays.
Click the Restart Proxy Server button to apply the changes.
