When you make configuration changes on a page accessed from > > and click on that page, the changes are saved to the browser cache. If your session expires or you close the browser session before you update the Access Gateway with the changes, the changes are lost.
The Configuration page ( > > ) allows you to control how your changes are saved so they can be applied with the update options (see Section 15.1, Viewing and Updating the Configuration Status).
If you have any configuration changes saved to the browser cache, use the following options to control what happens to the changes:
OK: To save the configuration changes to the configuration store, click . This allows you to return at a later time to review or modify the changes before they are applied. If your Access Gateways are clustered and you prefer to update them one at a time, you need to save the configuration change. This ensures that the changes aren’t lost before the last cluster member is updated. When your session times out or you log out, the configuration changes are flushed from the browser cache. If this happens before the changes have been applied to some servers in the cluster, the changes cannot be applied to those servers.
If you decide to cancel the saved changes, click the button and the saved configuration is overwritten by the last successfully applied configuration.
Cancel: To cancel changes that are pending in the browser cache, click the button. To cancel modifications to specific services, click the link by the service. The button does not affect the changes that have been saved to the configuration store.
Revert: To cancel any saved changes, click , then confirm the cancellation. The saved configuration is overwritten by the last successfully applied configuration.
If you have applied the changes to one member of the cluster, you cannot use the button to revert to the configuration you had before applying the changes. If you decide you do not want to apply these changes to other members of the cluster, remove the server that you updated with the changes from the cluster. Then click to cancel the saved changes. The members of the cluster return to the last successfully applied configuration. To apply this configuration to the removed server, add this server to the cluster.
The button does not cancel the following configuration changes:
Identity Server Cluster: If you change the option on the Reverse Proxy/Authentication page, then click on the Configuration page, the button cannot cancel this change. It is saved, and the next time you apply a configuration change, the Identity Server cluster configuration is applied. To cancel the change, you need to return to the Reverse Proxy/Authentication page, set the option to the original selection, then click on the Configuration page.

Port of the Reverse Proxy for the Embedded Service Provider: If you change the port of the reverse proxy that is used by the Embedded Service Provider (click > ), then click on the Configuration page, the button cannot cancel this change.

To cancel the change, return to the Reverse Proxy page, set the port to the original value, then click on the Configuration page.
Published DNS Name of the Proxy Service for the Embedded Service Provider: If you change the Published DNS Name of the proxy service that is used by the Embedded Service Provider (click > ), then click on the Configuration page, the button cannot cancel this change.

To cancel the change, return to the Proxy Service page, set the Published DNS Name to its original value, then click on the Configuration page.

If you change the server certificate for the reverse proxy (click > ) or change the Web server certificates (click > > > , the button cannot cancel these changes.
