asp.net Session expires early - asp.net

I have user log in logic in my web app. after successful log in, i set the user id in Session, so i can keep track of the user. and in my master file page load event, i do
Session.timeout = 60
so session should timeout after an hour. but my session times out at around 10 - 20 minutes. What am i doing wrong? i bet it's obvious.

It is probably due to your IIS settings. In IIS the default timeout for a session is 20 min.
Use the IIS manager to change it.

Have you tried setting it in your web.config instead of server side code?
<configuration>
<system.web>
<sessionState
mode="InProc"
cookieless="true"
timeout="60" />
</system.web>
</configuration>

If your app is crashing and re-starting at all, your sessions will be lost.
I'd setup some Health Monitoring and setup a notification for your app re-starting. If it happen more often than your 20 minutes then something is crashing your app.

Session timeout in asp.net on server

I have a asp.net website hosted on the server. On localhost session timeout is working but on server it is not working (Around only 5 min).
I am using following code.
<sessionState
mode="InProc"
timeout="100" />
Please help me.
In some cases, when you increase session timeout, then run web application, session will still expire. There could be few possible reasons for this.
Notice that session timeout should be less than Application pool idle timeout, so if you increase session timeout, you have to increase application idle timeout too. Otherwise, application will get recycled. If application is recycled, sessions will expire automatically.
Also, if you use Forms Authentication, you'll probably need to increase forms timeout too, using markup code in web.config like this:
<system.web>
<authentication mode="Forms">
<forms timeout="60"/>
</authentication>
...
</system.web>

How to troubleshoot MVC/Identity 2 authentication timeout

User authenticates, but is becoming unauthenticated within a minute or minutes. Seems to happen at random, but is within a handful of minutes.
Is there a breakpoint I can set someplace where logout is occurring , or a method of troubleshooting why a user is being logged out?
This doesn't seem to happen on localhost when running the project using VS, but is happening on the remote host after publishing.
Set the session state in IIS or the web.config:
<system.web>
<sessionState timeout="60"/>
...
That sets the timeout to be 60 minutes. You should also lookup session state modes.

Sessions and auth in asp.net

While deveoping a site (using Forms authentication and InProc sessionstate) a frequently run into a scenario where I lose the variables stored in Session (such as Session["myVar"]), but my auth-session remains valid.
This results in some wierd behavior on my site.
Why is this happening and what can I do to prevent diffrent lifecycles for my auth and my session variables?
In Asp.Net a Session and "Being logged in" are not the same thing.
Both are (usually) controlled by cookies, but the cookies are separate.
To control how long a Session is kept alive, please see answer by Jonas T.
To control how long a user remains logged in, you can use the timeOut on the <forms ... /> element:
<system.web>
<authentication mode="Forms">
<forms loginUrl="~/Account/Login.aspx" timeout="120" slidingExpiration="true"/>
</authentication>
...
</system.web>
To get rid of your problem you should make sure that the session timeout is at least as long as the forms authentication timeout.
If you are allowing persisted cookies in forms authentication ("Remember me"), then there are no gurantees. In that case you just have to set the session timeout to "long enough" according to some criteria/specification.
Edit: Also check the settings on your application pool (under IIS) where the site is deployed. And specifically check what the "Idle Time-out" is. If this is set low (default value is 20 minutes I think), then IIS will shut down the application pool if no request have come in during that time. That (of course) terminates whatever in-proc sessions existed.
Forms Authentication stores its ticket in Cookie at client side or URL(if cookie is disabled).
Session variables are stored at server side with expired time. If you want your variable to be more persistent use cookie.
You can extend your session time out in web config. This is for 20 minutes.
<configuration>
<system.web>
<sessionState timeout="20"></sessionState>
</system.web>
</configuration>
You said that you are working with ASP.NET Form authentication/authorization then I'd suggest you to use Profile instead of Session state.

ASP.NET Session TimeOut problem

I have a wired scenario in one of my ASP.net application.
I am using ASP.net membership with my custom "roleManager",
and having below tag in web.config to restrict any user not having role of "Keywords"(roles) to access "Keywords"(path) folder
<location path="Keywords">
<system.web>
<authorization>
<allow roles="Keywords"/>
<deny users="*" />
</authorization>
</system.web>
</location>
If any user with some other role allow to assess this URL (Keywords in this case) will be redirected to a custom- Access denied page.
Now things working fine but when I left my application with a inactivity of 30 min I am not able to visit the "Keywords", all the time I end up with the custom- Access denied page, if I close the browser, login again it start working fine.
Please help me in this case.
Thanks in advance
ASP.NET sessions time out after 20 minutes by default, I think.
You can extend this by specifying a longer time (in minutes) in the Web.config:
<system.web>
<sessionState timeout="60"/>
...
</system.web>
If you are authenticating via Forms, you should raise the authentication cookie timeout value to match.
Also bear in mind that, when running the site under IIS, you should probably extend the application pool's idle timout to something similar. If you don't do this, the HttpApplication instance for your ASP.NET site will be unloaded, destroying any active sessions in the process.
Usually, the first and easiest thing to do is just change the configuration/system.web/sessionState#timeout value to something like “90″
<sessionState timeout="90" />
it still appears to be timing out after 20 minutes.
*This doesn’t make any sense, it explicitly says that the session timeout should be exactly 90 minutes.*
There’s a couple of issues that are tied together here:
The application pool’s worker process default idle timeout is also
set to 20 minutes
The default mode of storing session state is in the IIS process
The settings for the application pool can be found by clicking Properties (IIS 6) or Advanced Settings (IIS 7.5) on the application pool that the application is assigned to.
Ensure the value of "Idle-Time-out(minutes)" is set to the timeout of your session, at a minimum (ex 90), to ensure that all sessions persist for the entire session timeout period.

Session timeout in ASP.NET

I am running an ASP.NET 2.0 application in IIS 6.0. I want session timeout to be 60 minutes rather than the default 20 minutes. I have done the following
Set <sessionState timeout="60"></sessionState>
in web.config.
Set session timeout to 60 minutes in IIS manager/Web site properties/ASP.NET configuration settings.
Set idle timeout to 60 minutes in application pool properties/performance.
I am still getting a session timeout at 20 minutes. Is there anything else I need to do?
Are you using Forms authentication?
Forms authentication uses it own value for timeout (30 min. by default). A forms authentication timeout will send the user to the login page with the session still active. This may look like the behavior your app gives when session times out making it easy to confuse one with the other.
<system.web>
<authentication mode="Forms">
<forms timeout="50"/>
</authentication>
<sessionState timeout="60" />
</system.web>
Setting the forms timeout to something less than the session timeout can give the user a window in which to log back in without losing any session data.
I don't know about web.config or IIS.
But I believe that from C# code you can do it like
Session.Timeout = 60; // 60 is number of minutes
Use the following code block in your web.config file.
Here default session time out is 80 mins.
<system.web>
<sessionState mode="InProc" cookieless="false" timeout="80" />
</system.web>
Use the following link for Session Timeout with popup alert message.
Session Timeout Example
FYI:The above examples is done with devexpress popup control so you need to customize/replace devexpress popup control with normal popup control. If your using devexpress no need to customize
In my situation, it was Application Pool. It is set to restart when idle for xx mins. When I set it to not restart, it seems to use value from Web Config.
Do you have anything in machine.config that might be taking effect? Setting the session timeout in web.config should override any settings in IIS or machine.config, however, if you have a web.config file somewhere in a subfolder in your application, that setting will override the one in the root of your application.
Also, if I remember correctly, the timeout in IIS only affects .asp pages, not .aspx. Are you sure your session code in web.config is correct? It should look something like:
<sessionState
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
stateNetworkTimeout="60"
sqlConnectionString="data source=127.0.0.1;Integrated Security=SSPI"
cookieless="false"
timeout="60"
/>
That is usually all that you need to do...
Are you sure that after 20 minutes, the reason that the session is being lost is from being idle though...
There are many reasons as to why the session might be cleared. You can enable event logging for IIS and can then use the event viewer to see reasons why the session was cleared...you might find that it is for other reasons perhaps?
You can also read the documentation for event messages and the associated table of events.
https://usefulaspandcsharp.wordpress.com/tag/session-timeout/
<authentication mode="Forms">
<forms loginUrl="Login.aspx" name=".ASPXFORMSAUTH" timeout="60" slidingExpiration="true" />
</authentication>
<sessionState mode="InProc" timeout="60" />
If you are using Authentication, I recommend adding the following in web.config file.
In my case, users are redirected to the login page upon timing out:
<authentication mode="Forms">
<forms defaultUrl="Login.aspx" timeout="120"/>
</authentication>
Since ASP.Net core 1.0 (vNext or whatever name is used for it) sessions are implemented differently.
I changed the session timeout value in Startup.cs, void ConfigureServices using:
services.AddSession(options => options.IdleTimeout = TimeSpan.FromSeconds(42));
Or if you want to use the appsettings.json file, you can do something like:
// Appsettings.json
"SessionOptions": {
"IdleTimeout": "00:30:00"
}
// Startup.cs
services.AddSession(options => options.IdleTimeout = TimeSpan.Parse(Config.GetSection("SessionOptions")["IdleTimeout"]));
You can find the setting here in IIS:
It can be found at the server level, web site level, or app level under "ASP".
I think you can set it at the web.config level here. Please confirm this for yourself.
<configuration>
<system.web>
<!-- Session Timeout in Minutes (Also in Global.asax) -->
<sessionState timeout="1440"/>
</system.web>
</configuration>
The default session timeout is defined into IIS to 20 minutes
Follow the procedures below for each site hosted on the IIS 8.5 web
Open the IIS 8.5 Manager.
Click the site name.
Select "Configuration Editor" under the "Management" section.
From the "Section:" drop-down list at the top of the configuration
editor, locate "system.web/sessionState".
Set the "timeout" to "00:20:00 or less”, using the lowest value
possible depending upon the application. Acceptable values are 5
minutes for high-value applications, 10 minutes for medium-value
applications, and 20 minutes for low-value applications.
In the "Actions" pane, click "Apply".
IIS sessions timeout value is for classic .asp applications only, this is controlled on IIS configuration.
In your case For ASP.NET apps, only the web.config-specified timeout value applies.
if you are want session timeout for website than remove
<authentication mode="Forms">
<forms timeout="50"/>
</authentication>
tag from web.config file.
The Timeout property specifies the time-out period assigned to the Session object for the application, in minutes. If the user does not refresh or request a page within the time-out period, the session ends.
IIS 6.0: The minimum allowed value is 1 minute and the maximum is
1440 minutes.
Session.Timeout = 600;
After changing the session timeout value in IIS, Kindly restart the IIS.
To achieve this go to command prompt. Type IISRESET and press enter.
