Is it possible to load data from a different domain?

Is it possible to load data from a different domain?

I posted this already but the post seems to have disappeared, so sorry if it's a duplicate.

I've looked through the form and can't find an answer to my question - can I make a call from one server to another to recieve some data?

I want to do something like this:
  1. var callAddress = "";//remote url added here

  2. var STUID = "";//user id param added here
  3. var tutID = "";//content identifier ID added here
  4. function getupdate(){
    callAddress = remoteaddress+"/admin/functions/getUsersData.asp?userid="+STUID+"&tutID="+tutid;
  5. //call to remote url
    $.get(callAddress, updateData);
    }
    function updateData(data){


  6. //data back from remote url
    alert(data);
    }

    $(document).ready(getupdate);





The idea is to load a users data from a central server, while the actual content can be on multiple domains. When I try the above I get the browser warning about accessing information beyond the pages control. I want to avoid this.

Maybe I need to recieve JSON data or something? No idea what I am doing wrong, but would gratefully appreciate any help or pointers.

Thanks
