I need to handle "session end" event for my web application when user closes his browser. Session is stored in Sql.
View 6 RepliesAll we have a global ships position tracking website which runs smoothly until IIS application pool recycles.When there is workerprocess recycling looks like session state expires as a result i loose all session data and when customer clicks refresh button he is redirected to login page.
In web.config Session state mode is set to InProc so i changed it to State Server but to my luck i have MAP object which is not serialiazable which is causing the maps from not appearing on the website.I tried adding serializable attribute to the object class but still not succesfull.Our website is accessed by our customers whose count is more than 1000.
Changing the session state mode from InProc to StateServer can really slow down the response time so
Is it good to go further fix the serailizable issues and move to state server?.
Is there any way I can retain my session data when application pool recyles?..
Stopping Application pool from recycling may not be a good idea considering health factor of web server.

I am very new to asp.net. I developed one application. In that I have two pages. First page contains Application.Get() in page load event, here I read this Application variable, initially it returns NULL. If it is NULL, I make some buttons invisible. Then I jump to second page, in that page contains Application.Set(). Again I jump from second page to first page, this time Application.Get() is not NULL, I make some buttons visible.This is ok, if I execute the program in .net software.
But, when I publish this same program to web server like IIS, it is not working properly. After publishing very first time the first page returns NULL after that it doesnt return NULL even I closed the browser. I dont know why. In program, I used 2.0 framework. IIS also has 2.0 framework. Please clear this issue.

User Interface: 2 Labels; 1 Buttons
Requirements: Create a Web Page in ASPx that will do the following:
1)One label will provide a count of how many times Button 1 has been clicked in the current session.
2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.

I am using a treeview in my master page and every node having link to its container page.That means click on any child node of treeview its redirect to another page by taking some value.
Now every time I click on nodes of treeview, its get collaps when child page loaded...
Now regaring maintain state of treeview across my web application...
We have a web site that implements a custom SiteMapProvider using a User Control added in the master page. I need to be able to limit the sitemap nodes added depending on the logged in user, that is, certain users should not see certain sitemap nodes. Currently, the login processing code determines if users are in the certain category or role and then sets a value in session state, for example, Session["UserInRoleXXX"] = "Yes"; I tried changing the code in the user control to check the session state, but I got the following error: NullReferenceException ... Object reference not set to an instance of an object." Can session state be accessed in a user control?
View 6 RepliesMy prior asp.net apps used windows authentication on an intranet. Now I'm developing an app for the internet and am stumbling over how to properly manage user sessions and state.
I first developed my web site functionality; created the SQL DB and got all of the pages to properly handle the data. Then, I installed the SQL Membership database and was able to get the CreateUser, Login, Logout pages to work. On the Verify process for the Userid, I added a step that will take the membership UserId value and create a Company record in my tables and link my CompanyId key with the UserId.
At Login time, I create a CompanyId session variable; each page uses it to retrieve records for the user. When Session Timeout occurs and the user click a link to another page, the app redirects properly to a Login page. However, if the time expires and then the user interacts on that same page, 'Object not set to an instance of the object' - the CompanyId session variable has expired.
What is the proper way to handle this? I'd like the page to automatically redirect to a TimedOut page (this would happen automatically without the user doing anything).
I considered writing a Function where I pass the Session variable I want and the Function sees if it exists; if it doesn't it would do a Response.Redirect to the TimedOut page...I can't get the Redirect to work in a Class Function ('reference to a non-shared member...').
I assumed that I should set CompanyId as a Session Variable so each page knows the user to get data for. Another approach is to use the membership User and if it is still valid, do a DB lookup to get the CompanyId. I did not choose this because I felt that it would increase DB traffic and web traffic.
Here are several relevant settings from my web.config:
<sessionState cookieless="UseDeviceProfile" />
<authentication mode="Forms">
<forms loginUrl="~/UserTasks/Login.aspx" />
It feels like there should be a straightforward answer to this but I am missing it.
we are experiencing big difficulties in the configuration of ASP.Net state service and II7. The service seems not working correctly because when the application pools recycles the applicatio loose the session.If we try the same configuration in IIS6 it works correcly.What is the correct way to configure the aspnet session state service in iis7?

I have one web application. In that, I have two pages. One is view/edit page and another one is login page. The view/edit page contains one edit button and one login button.
First I execute view/edit page, at that time I dont want to show edit button. When user clicks login button, the page will be redirected to login page, where the user has to enter username and password. If user enters both correct, again the page will be redirected back to view/edit page. This time, the edit button has to be shown to make some modifications, since the user is authenticated.
I tried this thing by using session with cookieless. It works perfectly but some times it shows web page not available. I made session timeout 120 minutes and cookieless is true. In URL session ID also available.
So, whats the alternate way to maintain user log state or whats wrong in web.config file.

Basically i have created a chat application. In which i have a moderator page.

Now as i am logged in as the moderator how do i delete the session of a particular user whom i want to block the chat from commencing.
I have two web applications and sometimes I need user to jump from one application to another. Since they are two web applications( websites) in the same machine, I can not share session between them.
The technical challenge for me is how to pass session information (I only need to pass userID string information in the session) from one source application to another destination application -- so that the user feels Single Sign On and personal information is displayed for him/her in both application (as the userID is passed to the destination application, no re-login is needed).
Another challenge is that when the user jumps to another URL in another application -- I just need to generate the common unified [URL]
