RE: FormsAuthentication Timeout not reset



Hi,

I'm using forms authentication with a 50 minute timeout and sliding
expiration.
The ticket expiration value is not being reset after greater than 25
minutes. I have session variables turned off.
I'm using roles and have the same experience whether I use role cookies or
not.
No async postbacks on the page.

I setup an nUnit test which postsbacks the page every minute.
I log the authentication ticket expiration time value every post.

The ticket.Expiration value is not changing.
After 50 minutes I am redirected to the login page.


I did a test following your description but I cannot reproduce this
problem. For test purpose I set timeout to one minute. Then I click the
button every few seconds. 30 seconds elapsed after the first page load and
the expire time is updated on the next postback. My test code is like below:

aspx.cs:

protected void Page_Load(object sender, EventArgs e)
{
FormsIdentity id = (FormsIdentity)HttpContext.Current.User.Identity;
var expire= id.Ticket.Expiration;
Response.Write("expiration:" + expire);
}

aspx:

<form id="form1" runat="server">
<div>

<input id="time" />
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>

<script type="text/javascript">
var seconds = 0;
function timedMsg() {
document.getElementById("time").value = seconds;
var t = setTimeout("timedMsg()", 1000);
seconds++;
}
var d = new Date();

var curr_hour = d.getHours();
var curr_min = d.getMinutes();
var curr_sec=d.getSeconds();
document.write(curr_hour + " : " + curr_min + ":" + curr_sec);

timedMsg();
</script>
</form>

web.config:

<forms loginUrl="Login.aspx" timeout="1" slidingExpiration="true">

</forms>

Could you please create a new project to test the above code? Does it work?

As far as I know it's unlikely that the internal mechanism of ASP.NET
breaks. Are you using custom HttpModule for authentication? Please read the
following article which describes a similar issue:

Please let me know your test result. We can then work together to do
further investigation.
