hi, i found out how to change the remote path, but it’s not by a hook filter.
in Cdn_Core.php
in function:
function build_file_descriptor( $local_path, $remote_path ) {
$file = array( ‘local_path’ => $local_path,
‘remote_path’ => “ortal-test/” . $remote_path,
‘original_url’ => $this->relative_path_to_url( $local_path ) );
$file = apply_filters( ‘w3tc_build_cdn_file_array’, $file );
return $file;
}
