| Authorization in the post-operation phase occurs on the server after the operation is complete and before the results are sent to the client. |
| |
| The callback can modify the results of certain operations, such as `query`, `get` and `keySet`, or even completely disallow the operation. For example, a post-operation callback for a query operation can filter out sensitive data or data that the client should not receive, or even completely fail the operation. |
| |
| The `security-client-accessor-pp` system property in the server’s `gemfire.properties` file specifies the callback to invoke in the post-operation phase. For example: |
| |
| ``` pre |
| security-client-accessor-pp=templates.security.XmlAuthorization.create |
| ``` |
