AJAX Failing when fetching data from another server

Question

I read AJAX does not work with remote but found solution but still facing How to do it with Pure AJAX, Any guide?? I searched a lot and tried some methods, but did not get. When I am using same IP and fetching data ,its working with warning,but when giving another server IP, it does not fetch .

function tooltipajax(r_ID) {
    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
    }
    else {
        // code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState==4 && xmlhttp.status==200) {
            document.getElementById('span'+ r_ID).innerHTML = xmlhttp.responseText;
        }
    }

    xmlhttp.open("GET","http://ip here/common/accounteditajax.php?key=" +r_ID,true);
    xmlhttp.send();
}

I tried HEADER

header("Access-control-Allow-Origin: http://IP HERE/common/");

it worked for local server with ip with warning Cannot modify header information - headers already sent by (output started at

But not working with another server ip..

read the warning: the header is not being sent so the browser is not allowing the request because it did not receive the header, you need to place the header call before anything is output — user1937198, May 21 '13 at 16:51
but my ajax is above to php code and header is put in php code,so how to manage that? — learning_programming, May 21 '13 at 16:53
either move the php code or use a proxy so you dont need to do a cross site request — user1937198, May 21 '13 at 16:55
why do you need to do an ajax request to this other IP, there is probably a better way — user1937198, May 21 '13 at 16:57
AJAX http requests have a something called `SAME DOMAIN POLICY` meaning, that you can not fetch/post data other than under the domain you are working on — samayo, May 21 '13 at 17:00
I am having client where information on mouse over, I want to send from my server.Please tell me what way other? — learning_programming, May 21 '13 at 17:00
is there any reason the information can't be on the same server as the html page,(cdn, third party api) — user1937198, May 21 '13 at 17:04
@user, there is no reson for that, but I have 100 clients , I want to change content several times for mouseover, so i wont change on 100 servers — learning_programming, May 21 '13 at 17:06
@orangepill I read JSONP, but unable to do that becuase I have implemented all code with ajax:( — learning_programming, May 21 '13 at 17:07
@learning_programming are you trying to fetch from your own server or another? — samayo, May 21 '13 at 17:13
