Do you really need to keep the session (do you have data in it?) or is it enough to fake this by reinstantiating the session when a request comes in? If the first, use the method above. If the second, try something like using the Session_End event handler.

If you have Forms Authentication, then you get something in the Global.asax.cs like 

<pre><code>FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(formsCookie.Value);
if (ticket.Expired)
{
 Request.Cookies.Remove(FormsAuthentication.FormsCookieName);
 FormsAuthentication.SignOut();
 ... 
 }
else
{ ...
 // renew ticket if old
 ticket = FormsAuthentication.RenewTicketIfOld(ticket);
 ...
 }
</code></pre>

And you set the ticket lifetime much longer than the session lifetime. If you're not authenticating, or using a different authentication method, there are similar tricks. Microsoft TFS web interface and SharePoint seem to use these - the give away is that if you click a link on a stale page, you get authentication prompts in the popup window, but if you just use a command, it works.

Whenever you make a request to the server the session timeout resets. So you can just make an ajax call to an empty HTTP handler on the server, but make sure the handler's cache is disabled, otherwise the browser will cache your handler and won't make a new request.

KeepSessionAlive.ashx.cs

<pre><code>public class KeepSessionAlive : IHttpHandler, IRequiresSessionState
 {

 public void ProcessRequest(HttpContext context)
 {
 context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
 context.Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
 context.Response.Cache.SetNoStore();
 context.Response.Cache.SetNoServerCaching();
 }
 }
</code></pre>

.JS:

<pre><code>window.onload = function () {
 setInterval("KeepSessionAlive()", 60000)
}

 function KeepSessionAlive() {
 url = "/KeepSessionAlive.ashx?";
 var xmlHttp = new XMLHttpRequest();
 xmlHttp.open("GET", url, true);
 xmlHttp.send();
 }
</code></pre>

@veggerby - There is no need for the overhead of storing variables in the session. Just preforming a request to the server is enough.

Here is a alternative solution that should survive if the client pc goes into sleep mode.

If you have a huge amount of logged in users then use this cautiously as this could eat a lot of server memory.

After you login (i do this in the LoggedIn event of the login control)

<pre class="lang-vb prettyprint-override"><code>Dim loggedOutAfterInactivity As Integer = 999 'Minutes

'Keep the session alive as long as the authentication cookie.
Session.Timeout = loggedOutAfterInactivity

'Get the authenticationTicket, decrypt and change timeout and create a new one.
Dim formsAuthenticationTicketCookie As HttpCookie = _
 Response.Cookies(FormsAuthentication.FormsCookieName)

Dim ticket As FormsAuthenticationTicket = _
 FormsAuthentication.Decrypt(formsAuthenticationTicketCookie.Value)
Dim newTicket As New FormsAuthenticationTicket(
 ticket.Version, ticket.Name, ticket.IssueDate, 
 ticket.IssueDate.AddMinutes(loggedOutAfterInactivity), 
 ticket.IsPersistent, ticket.UserData)
formsAuthenticationTicketCookie.Value = FormsAuthentication.Encrypt(newTicket)

The <code>(20-1)*60*1000</code> is refresh time, it will refresh the session timeout. Refresh timeout is calculated as default time out of iis = 20 minutes, means 20 × 60000 = 1200000 milliseconds - 60000 millisecond (One minutes before session expires ) is 1140000.

I spent a few days trying to figure out how to prolong a users session in WebForms via a popup dialog giving the user the option to renew the session or to allow it to expire. The #1 thing that you need to know is that you don't need any of this fancy 'HttpContext' stuff going on in some of the other answers. All you need is jQuery's $.post(); method. For example, while debugging I used:

<pre><code>$.post("http://localhost:5562/Members/Location/Default.aspx");
</code></pre>

and on your live site you would use something like:

<pre><code>$.post("http://mysite/Members/Location/Default.aspx");
</code></pre>

It's as easy as that. Furthermore, if you'd like to prompt the user with the option to renew their session do something similar to the following:

<pre><code> &lt;script type="text/javascript"&gt;
 $(function () { 
 var t = 9;
 var prolongBool = false;
 var originURL = document.location.origin;
 var expireTime = &lt;%= FormsAuthentication.Timeout.TotalMinutes %&gt;;

 // Dialog Counter
 var dialogCounter = function() {
 setTimeout( function() {
 $('#tickVar').text(t);
 t--;
 if(t &lt;= 0 &amp;&amp; prolongBool == false) {
 var originURL = document.location.origin;
 window.location.replace(originURL + "/timeout.aspx");
 return;
 }
 else if(t &lt;= 0) {
 return;
 }
 dialogCounter();
 }, 1000);
 }

 var refreshDialogTimer = function() {
 setTimeout(function() { 
 $('#timeoutDialog').dialog('open');
 }, (expireTime * 1000 * 60 - (10 * 1000)) );
 };

 refreshDialogTimer();

 $('#timeoutDialog').dialog({
 title: "Session Expiring!",
 autoOpen: false,
 height: 170,
 width: 350,
 modal: true,
 buttons: {
 'Yes': function () {
 prolongBool = true;
 $.post("http://localhost:5562/Members/Location/Default.aspx"); 
 refreshDialogTimer();
 $(this).dialog("close");
 },
 Cancel: function () {
 var originURL = document.location.origin;
 window.location.replace(originURL + "/timeout.aspx");
 }
 },
 open: function() {
 prolongBool = false;
 $('#tickVar').text(10);
 t = 9;
 dialogCounter();
 }
 }); // end timeoutDialog
 }); //End page load
&lt;/script&gt;
</code></pre>

Don't forget to add the Dialog to your html:

<pre><code> &lt;div id="timeoutDialog" class='modal'&gt;
 &lt;form&gt;
 &lt;fieldset&gt;
 &lt;label for="timeoutDialog"&gt;Your session will expire in&lt;/label&gt;
 &lt;label for="timeoutDialog" id="tickVar"&gt;10&lt;/label&gt;
 &lt;label for="timeoutDialog"&gt;seconds, would you like to renew your session?&lt;/label&gt;
 &lt;/fieldset&gt;
 &lt;/form&gt;
 &lt;/div&gt;
</code></pre>

In regards to veggerby's solution, if you are trying to implement it on a VB app, be careful trying to run the supplied code through a translator. The following will work:

<pre><code>Imports System.Web
Imports System.Web.Services
Imports System.Web.SessionState

Public Class SessionHeartbeatHttpHandler
 Implements IHttpHandler
 Implements IRequiresSessionState

 ReadOnly Property IsReusable() As Boolean Implements IHttpHandler.IsReusable
 Get
 Return False
 End Get
 End Property

 Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest
 context.Session("Heartbeat") = DateTime.Now
 End Sub
End Class
</code></pre>

Also, instead of calling like heartbeat() function like:

<pre><code> setTimeout("heartbeat()", 300000);
</code></pre>

Instead, call it like:

<pre><code> setInterval(function () { heartbeat(); }, 300000);
</code></pre>

Number one, setTimeout only fires once whereas setInterval will fire repeatedly. Number two, calling heartbeat() like a string didn't work for me, whereas calling it like an actual function did.

And I can absolutely 100% confirm that this solution will overcome GoDaddy's ridiculous decision to force a 5 minute apppool session in Plesk!

Which is the easiest and most unobstrusive way to keep an ASP.NET session alive as long as the user has the browser window open? Is it timed AJAX calls? I want to prevent the following: sometimes users keep their window open for a long time, then enter stuff, and on submit nothing works anymore because the server side session expired. I don't want to increase the timeout value for more than 10 min on the server as I want closed sessions (by closing the browser window) to time out fast.

Suggestions, code samples?
