Pulling data across domains

Question

Hello. I have hit a real deadend with this problem. I would
appreciate some help.
I have designed a website in Flash (
http://www.clarkhulings.com).
Under "Store" on the navigation bar, it contains a PayPal "View
Cart" button that is not working. This is because the Flash does
not allow direct access to data on the PayPal site. For security
reasons, a Macromedia Flash movie playing in a web browser is not
allowed to access data that resides outside the exact web domain
from which the SWF originated. See

I have created a crossdomain.xml file and added it to the
webserver of clarkhuling.com. The file looks like this:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "
http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*.paypal.com"
secure="false"/>
</cross-domain-policy>
Because clarkhulings.com is not using SSL and PayPal is, I
have used secure="false" in the code above.
My Actionscript code that is attached to the View Cart
button, looks like this:
view_cart_btn.onRelease = function() {
var paypal_lv:LoadVars = new LoadVars();
paypal_lv.onLoad = function(p_success:Boolean) {
if (p_success) {
for (var i in this) {
trace("PayPal Responce "+i+": "+this
} else {
trace("PayPal Responce: Error connecting to server.");
paypal_lv.cmd = "_cart";
paypal_lv.business = "[email protected]";
paypal_lv.display = "1";
paypal_lv.page_style = "hulings";
paypal_lv.sendAndLoad("https://www.paypal.com/cgi-bin/webscr",
paypal_lv, "POST");
As you can see, by going to the website (
http://www.clarkhulings.com),
clicking "View Cart" under STORE does not work. What am I doing
wrong? I would appreciate the help of more learned developers out
there!

الحمد لله
thanks for Allah,
and thans for Justin "Cartoon Smart" http://www.cartoonsmart.com/
i fix this problem using the proxy file which he upload with the RSS Reader tutorial,
http://www.cartoonsmart.com/rss_reader.html
so, for any people who have the same problem which is called
Loading data across domains
here you are the solution,
i used the proxy.php file
just Note if you are using Flash Player 10, you must upload it in the root domain
like :
www.yourdomain.com/proxy.php
Note that you don't need to make any modefications to this file at all, just upload it as it is
then you point to it in the flash file or in the XML fle which you control the flash form it,
im my case i control the flash form a xml file called controls.xml and i make variable to load rss feeds from a variable in it called LinkRss
so in this file i must point to the feed using this way
Code:
LinkRss="http://www.yourdomain.com/proxy.php?url=http://rss.news.yahoo.com/rss/topstories"
sure you will change yourdomain to be any domain name you are putting the flash in it,
for example
Code:
LinkRss="http://www.cartoonsmart.com/proxy.php?url=http://rss.news.yahoo.com/rss/topstories"
that's all,
