Hi Masi,

this technic you find in xajax_tutor. Although your theory is fine it
seems to work within USER_INT. Maybe the head is not cached. Just a
guess. :-)

$cssFile = $configuration['cssFile'];
$absPath = t3lib_div::getFileAbsFileName($cssFile);
$relPath = substr($absPath, strlen(PATH_site));	
		$GLOBALS['TSFE']->additionalHeaderData['tx_resultbrowser']
  = '<link rel="stylesheet" type="text/css" href="'. $relPath . '" />';
