[TYPO3] xajax and realurl

[Rens Admiraal]

Hi all,

Sorry for posting again, but I've still 1 problem left while getting  
my extension compatible with real_url.
It seems that xajax doesn't work with real_url. When I do a xajax  
request I get the error 'there is whitespace in your response'

The exact same code works perfectly in a typo3 installation without  
real_url. Maybe I need to make some exteption in my localconf.php  
or .htaccess file, but I can't find any information on google...

Does anyone know if I have to make changes to my real_url, or  
something else, and what those changes are???

This is my code I use to make the xajax request:
$objResponse->addAssign('itemprijs[' . $uid . ']', 'innerHTML', $this- 
 >bedrag($productprijs));
$objResponse->addAssign('btwbedrag', 'innerHTML', $this->bedrag 
($btw));		
$objResponse->addAssign('totaalprijs', 'innerHTML', $this->bedrag 
($totaalprijs));		
$objResponse->addAssign("ajax_error", "innerHTML", "");
$objResponse->addAssign('aantal_producten', 'innerHTML', $this- 
 >countProductsInCart());
$objResponse->addAssign('item[' . $uid . ']', 'value', '' . $aantal);
$objResponse->addScript("checkMinimumPrice(" . $this- 
 >getMinimumOrderSize() . ")");
	//return the XML response
return $objResponse->getXML();

removing all the addAssign / addScript lines still gives the same  
error...

This is my localconf.php code for real_url:
