handle jquery ajax redirect

I'm making a $.get to call a service 'A'. Service 'A' returns plain text which I display on the page. But sometimes it redirects to service 'B' which returns plain text. But, I'm unable to handle the response text of service 'B'. How do I do that?

I can not prove, but I hope that this script can guide you to a solution:

you would have to prove your status differences or text on each type of response from "a.php"

$.ajax({
  type: "GET",
  url: "a.php",
  complete: function (XMLHttpRequest, textStatus) {
     if (XMLHttpRequest.status!=200) // or responseText 
     { 
       var fn = arguments.callee;
       var _this = this;
       setTimeout(function(){fn.call(_this, XMLHttpRequest, textStatus);}, 200);
     }
     else
     {
       //ok
     }
  }
});

or EDIT:

  complete: function xCompleteFunction(XMLHttpRequest, textStatus) {
     if (XMLHttpRequest.status!=200) // or responseText 
     { 
       var _this = this;
       setTimeout(function(){xCompleteFunction.call(_this, XMLHttpRequest, textStatus);}, 200);
     }
     else
     {
       //ok
     }
  }

function call to itself

EDIT II:

redirect.html:

<html xmlns="http://www.w3.org/1999/xhtml">

<title></title>
<script type="text/javascript">
$(function(){
    $("#senddata").click(function(){
        $.ajax({
            type: "GET",
            url: "a.php",
            complete: function xCompleteFunction(XMLHttpRequest, textStatus) {
                $("#info").append(""+XMLHttpRequest.status+"<br />"+XMLHttpRequest.responseText+"<br>");
                if (XMLHttpRequest.status==301) // or responseText 
                { 
                    var _this = this;
                    setTimeout(function(){xCompleteFunction.call(_this, XMLHttpRequest, textStatus);}, 200);
                    $("#info").append("waiting redirect<br>");
                }
                else
                {
                    $("#info").append("redirect ok<br>");
                }
            }
        });
    });
});
</script>
</head>
<body>
<button id="senddata">send ajax request</button>
<pre id="info"></pre>
</body>
</html>

a.php:

<?php
for($a=0;$a<1000000;$a++)
{
    //wait
}
header('Location: b.php');

b.php:

<?php
    print "hola mundo";
