session variable gets lost

Hi! I have a session variable, and I set the Session.timeout=120; but after a while (not even 30 mins )it got lost and had errors cause of that in the app_code, where I have a function that takes as parameter the session variable value. Thank for any advice.

Firstly make sure you are never overwriting the session variable.

Another thing would be if the web server is low on resources it may drop some session items.

Make sure in the web.config file the session timeout is set properly

     <sessionState timeout="120"/>

Hi! I put this in the web config:





sqlConnectionString="data source=;Integrated Security=SSPI"










Now, if I set the timeout= "1" the session ends after 1 min, but if I set the timeout= 60 it ends at 20 mins. It seems like if I set the timeout less than 20 min it works, but If I set it to more than 20 mins it doesnt work. Any help appreciated.

I just tested the session timing again and it exipred after 10 mins, maybe less, but When I checked after 10 min it was gone.

in this situation where  you needs to store many values ,and each one has different period to stay in memory

you need to  use the cache instead ,

by using cache, you can specify the  period of time that the value must stay in there before destroyed,

the following link will be helpful for you:

 Hope it helps

After a looong night managed to change Session mode from inProc to SQLServer but still can't get the session variables to be saved
Hi,  I ran my Shopping Cart project and somehow everything worked fine(while in inProc), session variables were saved fine. I made some changes to my project and since then keep getting null session variables, no matter what I do. It took me the whole night to figure out how to turn to SQLServer mode,  marked custom classes as 'Serializable' with [Serializable] before the class definition but everything's in vain. Getting the same damned 'nulls' instead of the saved objects. private void Page_Load(object sender, System.EventArgs e)         {...

Session variable value gets lost
I am using 3.0 with C#. My web application requires some values that is used across my User Controls. These values are pertaining to the login user name and User type.

State management upon session variable changes
I noticed that whenever a session variable is changed...the application knows about it and suddenly restarts session. My question is does restart "ALL" sessions or only the active sessions for which the variables changed? Imagine a "multi-user" application all with different states and an administration panel that lets you change session variables.  In this case, my question has to do with the question that if Company X changes his session variables, will only Company X's sessions be reset or will all "sessions" be reset?  Hope that makes sense. ...

Session state keeps getting lost it seems....
I've had this problem for months it seems and I still haven't figured it out... I have a large, complex SQL-driven web application with 100 or so users. Every once in awhile users randomly get logged out and I think it's because the session is getting reset. I can't figure out why. I figured out one thing that was part of the problem. I was updating the system constantly, changing dozens of relatively large files at a time, and from what I read, if you do that too oftenASP will eventually run out of ram and reset itself, losing the session state. Apparently ASP doesn't get rid of the ...

Session variables vs. Session States
What is the difference and in what situations are they used. Thanks, Mattypee A session state (the state of your session) holds your session variables. If your session state expires (due to inactivity) then you lose your session variables...and any other info stored for that session. If you need to store USER specific information within a web app, then session variables are one(of several) ways to do it. MajorCatsMajorCats Is there any code that you could show that would give an example? Thanks, Mattypee example of what? reading and writing session variables? ...

Good news for those of you who get "Unable to make the session state request to the session state server." error..
Dear all,Due to the known problem of session variables getting lost if using InProc-server during frequent changes in development, I had to choose between SQL and ASP.NET State server, so I opted for the second. Initially, all fine, but after using it for a few days, I started to get this error: Server Error in '/cv2' Application.Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same.  If the server is on a remote machine, please ensure that it accep...

Session State Variables across multi sessions
I am having an issue where I save my DataTable into a Session Variable:   Session["dtDMFile"] = dtDMFile; Different users can use the web form that I created. Once the data is loaded,I send the DataTable to the session variable. My problem is that when I go to reload the data in the table, it is taking the data from the last user who stored the DataTable instead of from the particular user on their browser. For instance, User 1 (machine 1) loads data with field contents of: field1  field2  field3 User 2 (machine 2), then loads data with field contents of: f...
