AJAX call program from another server

[syok90]

i'm doing a lot of AJAX PROGRAM in my website
1. madads.myadswor ld.com
2. eshop.myadsworl d.com
3. syokchat.myadsw orld.com

i just want to ask:
can i call my php program from another server.normal way getjumrek.php program is in same server. Can i write var gettxt = http://192.168.1.40/getjumrek.php (this case current server is 192.168.1.41 but there is also getjumrek.php in 192.168.1.40)

example

[CODE=javascript]var gettxt = "getjumrek.php" ;
var httpReceive5Txt = getHTTPObject() ;
function receivetxt() {
//alert('aa');
if (httpReceiveTxt .readyState == 4 || httpReceiveTxt. readyState == 0) {
httpReceiveTxt. open("GET",GetT xt + '?lastkey=' + lastkey, true);
httpReceiveTxt. onreadystatecha nge = handlehHttpRece iveTxt;
httpReceiveTxt. send(null);
}
}



//deals with the servers' reply to requesting new content
function handlehHttpRece iveTxt() {
}

getHTTPObject() {}[/CODE]

Standard AJAX calls can not be cross domain, so you can only call to the same server.
