javascript window.location 和 IE 会话变量丢失

我在使用 javascript 时使用 Internet Explorer (IE 9) 时丢失会话变量窗口定位函数。

我注意到之前的页面和之后的页面显示相同的会话ID；但是即使会话 ID 相同，当发生重定向时，会话变量也会丢失。我还注意到，这种情况在 IE 中并不是每次都会发生，只是偶尔发生（随机）。使用 Chrome 时我没有遇到任何问题。

实时应用程序在这里：http://apps.facebook.com/zabeachwatch/ （当您观看视频时，它应该超时并在一段时间过后将您重定向回来。如果您到达注册页面，则意味着会话变量已丢失。通过 facebook 访问页面时不应发生这种情况）

是否有其他方法可以重定向计时器事件？

下面是导致重定向的代码片段。（window.location...）

<%
String cat = request.getParameter("cat");
String back_url = "CameraList.jsp?cat=" + cat;
back_url = response.encodeURL(back_url);
%>



<script type="text/javascript" language="javascript">
<!--
 var winW = 630, winH = 460;

function delayer(){
var s = "<%=back_url%>";
window.location.href = s;
return true;
}

<body id="images" style="background: rgb(197,204,211) 
 url(images/stripes.png);" onload="setTimeout('delayer()', 30000);

原文

I am loosing session variables when using Internet Explorer (IE 9) when using the javascript
window.location function.

I have noticed that the page before and the page after displays the same session ID; but the
session variables are lost when the redirect occurs even if the session ids are the same.
I have also noticed that this does not happen each and every time in IE, only some times(Random).
With Chrome I experience no problems.

The live application is here: http://apps.facebook.com/zabeachwatch/
(When you view the Video it should time-out and redirect you back after some time has elapsed.
If you land up on a registration page, this means that the session variables have been lost. This should not happen when accessing the page via facebook)

Is there perhaps some other way to redirect on a timer event?

Below is a snippet that causes the redirect.(window.location...)

<%
String cat = request.getParameter("cat");
String back_url = "CameraList.jsp?cat=" + cat;
back_url = response.encodeURL(back_url);
%>



<script type="text/javascript" language="javascript">
<!--
 var winW = 630, winH = 460;

function delayer(){
var s = "<%=back_url%>";
window.location.href = s;
return true;
}

<body id="images" style="background: rgb(197,204,211) 
 url(images/stripes.png);" onload="setTimeout('delayer()', 30000);
