如何在 fbml 应用程序中访问 facebook 会话 ID？

我正在开发一个可以添加到粉丝页面的 fbml 应用程序。然后应用程序将 ajax 请求发送到我的 php 脚本以获取数据等。我必须在我的 php 端针对密钥或在整个 facebook 会话期间保持不变的东西存储一些数据。我怎样才能实现这个？有没有办法在ajax请求中发送facebook会话id？我正在使用 fbml Ajax() 元素发送 ajax 请求。这是代码的一瞥

function do_ajax(path)
{   
    var sessionKey = '###'; //Something representing fbml app's session state
    var ajax = new Ajax();
    ajax.responseType = Ajax.FBML;
    ajax.ondone = function(data) {      
        document.getElementById('content').setInnerFBML(data);
    }  
    ajax.post(path+'/'+sessionKey);
}

访问者可能已登录，也可能未登录，因此我无法使用用户 ID。并且 php session id 在每个请求中不断变化。多谢

I am working on an fbml application which can be added to a fan page. The application then sends ajax request to my php script for data etc.
I have to store some data on my php side against a key or something which remains the same throughout facebook session. How can I implement this? Is there any way to send facebook session id in ajax request? I am using fbml Ajax() element to send ajax request.
Here's a glimpse of code

function do_ajax(path)
{   
    var sessionKey = '###'; //Something representing fbml app's session state
    var ajax = new Ajax();
    ajax.responseType = Ajax.FBML;
    ajax.ondone = function(data) {      
        document.getElementById('content').setInnerFBML(data);
    }  
    ajax.post(path+'/'+sessionKey);
}

The visitor may or may not be logged in so I can't use userid. And php session id keeps changing in each request.
Thanks a lot
