Sessionwill not expire if you keep on calling server side code. The sessiontime out will be resetting on each request to server. On subsequent requests to the same web site, the browser supplies the ASP.NET_SessionId Cookiewhich the server side module uses to access session value(like user information).
Session如果您继续调用服务器端代码，则不会过期。该session超时将被重新对每个请求到服务器。在对同一网站的后续请求中，浏览器提供ASP.NET_SessionId Cookie服务器端模块用于访问会话值（如用户信息）的 。

Until a session variable is established, a new session id is generated for every post back.
在建立会话变量之前，每次回发都会生成一个新的会话 ID。

Session ID which is saved in the cookie by default, is sent for every AJAX as well as non AJAX request. Hence the server is aware that the session user is active. Don't take my word for it. Use fiddler or the F12 tool within ie. You can see the cookies being sent out with every AJAX GET/POST request.
默认情况下保存在 cookie 中的会话 ID，为每个 AJAX 以及非 AJAX 请求发送。因此服务器知道会话用户是活动的。不要相信我的话。在 ie 中使用 fiddler 或 F12 工具。您可以看到随每个 AJAX GET/POST 请求发送的 cookie。

This will depend on a lot of factors so I suggest you run a test like below. It really takes less than 5 minutes to find out if your exact situation works in your environment. Here is my code that I used to test this, I use Telerik controls to test the idea but I added a .get to get the exact answer you wanted. aspx page has
这将取决于很多因素，因此我建议您进行如下测试。真正需要不到 5 分钟的时间才能确定您的确切情况是否适用于您的环境。这是我用来测试的代码，我使用 Telerik 控件来测试这个想法，但我添加了一个 .get 以获得您想要的确切答案。aspx页面有
<telerik:RadScriptManager ID="RadScriptManager1" Runat="server">
</telerik:RadScriptManager>
<telerik:RadAjaxManager ID="ram" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="btnFake">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="lblAnswer" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>
<script src="Scripts/jquery-1.4.1-vsdoc.js"></script>
<script>
$(document).ready(function () {
setTimeout(function () { document.location.href = "default.aspx?next"; }, 61000);
setInterval(function () {
var divForTimer = $("#divTime");
var secs = parseInt(divForTimer.html());
secs = secs + 1;
$("#divTime").html(secs.toString());
}, 1000);
});
function getPage() {
$.get("test.aspx", function(result) {
$("#btnFake").val("Got it");
});
}
</script>
<asp:Label ID="lblAnswer" runat="server"></asp:Label>
<Asp:button ID="btnTest" runat="server" Text="Renew" onclick="btnTest_Click" />
<input type="button" ID="btnAjaxget" onclick ="getPage()" value="Ajax get" />
<asp:Button ID="btnFake" runat="server" Text ="Fake it"
onclick="btnFake_Click"/>
<div id="divTime">1</div>
the .cs page has
.cs 页面有
protected void Page_Load(object sender, EventArgs e)
{
Session.Timeout = 1;
if (EMSG.CommonFunctions.GetSession("test").Length > 0)
{
this.lblAnswer.Text = "Session=" + EMSG.CommonFunctions.GetSession("test");
}
else
{
this.lblAnswer.Text = "No session";
}
}
protected void btnTest_Click(object sender, EventArgs e)
{
Session["test"] = "variable set";
this.lblAnswer.Text = Session["test"].ToString();
}
protected void btnFake_Click(object sender, EventArgs e)
{
lblAnswer.Text = "Ajax called.";
}
---you can arrange the above to fit your situation. But the idea is simple. You load the page. Click on the "Renew" button and this will set your session. Wait 61 seconds and the page will refresh and the session variable is gone. Try it again but this time click on one of the other two buttons after a few seconds and when the page refreshes you will see that the session variable has stayed intact from the ajax calls. The ajax call in this situation refreshes the session variable.
---您可以根据自己的情况安排上述内容。但这个想法很简单。你加载页面。单击“续订”按钮，这将设置您的会话。等待 61 秒，页面将刷新并且会话变量消失。再试一次，但这次在几秒钟后单击其他两个按钮之一，当页面刷新时，您将看到会话变量从 ajax 调用中保持不变。这种情况下的ajax调用会刷新会话变量。
