Hi,

I don't know if this might help (in fact, I am not sure whether what I say 
makes any sense at all), but usually you don't POST your parameters 
("cartmode=crtget") in the source URL (that is how GET works).

You might try replacing POST with GET (I've heard it might have weirds 
effects with caching), or else pass the arguments when you call send:

 function getCart() {
     var req = newXMLHttpRequest();
      req.onreadystatechange = getReadyStateHandler(req, updateCart);
      req.open("POST", "common/ManageCart", true);
      req.setRequestHeader("Content-Type", 
"application/x-www-form-urlencoded");
      req.send("cartmode=crtget");
 }

Perhaps other browsers HTTPRequest do some sort of trickery with the 
arguments which Chroe doesn't.


Good Luck.
