POIE cross domain ajax invocation XDomainRequest error

Body
copied!<p>I have to use the following code to logout from a page in an Iframe</p> <pre><code>//The javascript code is in a page in my-domain //it tries to logout from the page in other-domain $(window).unload(function() { if ($.browser.msie && window.XDomainRequest) // IE { var xdr = new XDomainRequest(); if (xdr) { xdr.onerror = function(){alert("XDR onerror");}; xdr.ontimeout = function(){alert("XDR timeout");}; xdr.onprogress = function(){alert("XDR onprogress");}; xdr.onload = function(){alert("XDR onload");}; xdr.timeout = 5000; xdr.open("GET", 'http://other-domain/.../j_spring_security_logout'); alert("before send"); xdr.send(); alert("after send"); } else alert('Failed to create new XDR object.'); } else // firefox $.getJSON( 'http://other-domain/.../j_spring_security_logout?callback=?', null); }); </code></pre> <p>However, I get alter boxes in IE8 in the this order: "before send", "XDR onerror", "after send".</p> <p>I have the following code in server side</p> <pre><code>@Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletResponse response = (HttpServletResponse) res; response.setHeader("Access-Control-Allow-Origin", "*"); response.setHeader("Access-Control-Allow-Methods", "GET,POST,OPTIONS"); response.setHeader("Access-Control-Max-Age", "360"); response.setHeader("Access-Control-Allow-Headers", "x-requested-with"); chain.doFilter(req, res); } </code></pre> <p>I can verify that the logout works perfect for Firefox after I use $.getJSON and response.setHeader("Access-Control-Allow-Origin", "*") and so on; however it doesn't logout when I use IE.</p> <p>Then I found this comment online:</p> <pre><code>"For cross-domain, IE requires you to use XDomainRequest instead of XMLHttpRequest. jQuery doesn't do it so you have to do it manually:" </code></pre> <p>So I added XDomainRequest. However, I got my alert dialog "XDR onerror" in IE8. What should I add to make this cross domain call in IE?</p>
