- How to ensure my application uses redirection with this extension to connect to Azure Database for MySQL?
Answer: Set mysqlnd_azure.enableRedirect=on The option value "on" will enforce redirection and return error if the configuration is wrong, e.g. the connection is not configured with SSL.
- How to verify the connection is currently using redirection?
Answer: For mysqli interface, check the "host_info" property of the connection object. For PDO interface, check the "PDO::ATTR_CONNECTION_STATUS" attribute. If the connection is using redirection, the content will be different from the host info you used to connect. Otherwise, it should contains the same value.
