Hy,

solution for my question is to set a new header in the calling file / class.
To avoid getting two headers while the first one produces a 404 Error 
for the calling class I set also a 302 Header (Redirect), so only one 
file for the frameset is submitted to the browser:

// setting parameters and build URL
$script = 
'../'.$GLOBALS['TYPO3_LOADED_EXT']['myExt']['siteRelPath'].'modX/myContentScript.php';
$nav = 
'../'.$GLOBALS['TYPO3_LOADED_EXT']['myExt']['siteRelPath'].'modX/myTreeView.php';

$URL_nav = 
htmlspecialchars($nav.'?currentSubScript='.rawurlencode($script));

// setting Headers
header("HTTP/1.0 302 Redirect");
header('Location: '.$BACK_PATH.'alt_mod_frameset.php?'.$URL_nav);

This Method you can use from any class and doesn't need further 
configuration of any variables.

If you get any 404-Errors:
- check the path-values for your files (pathes for your own files have 
to be noted relative to /typo3/- directory)
- check the signs '?' and '&' in your URL (often between the URL and the 
parameters a "&" may be noted instead of "?")
