The remote connector was introduced in version 1.2 to work with Masked Redirection. To use the remote connector, you must include it in your webtemplate.zip. 

Before including the connector files, make sure to modify the $hash variable inside the connector_settings.php file, this need to match the Masked Redirection Hash in the Module Options. 

Both connector_settings.php and connector.php are not encoded, you may customize any changes you need.
