I have a web application which uses a session variable to store the logged in userid. If no user is logged in, of course this variable will be empty and the contents displayed on my website are meant for guests. If there is a user logged in, the user specific controls/access/links will then be a displayed.
I am now having issues with my hosting where on shared application pool, the worker recycle is triggered every 90 minutes, this will clear sessions causing all my users to be logged out. I opted for a dedicated application pool, which got worse because I am only allocated 50MB memory limit and if this is reached, the worker recycle is triggered and I lose my sessions again. I have tried as much as possible optimization techniques, e.g. dispose where possible, close connections, disable viewstate for static controls etc but my memory per instance keeps building up from page to page without any signs of improvement. I don't use loops nor store huge objects like bitmaps etc but my sessions are now gone even faster than 90 minutes in shared application pool before.
I have considered using SQL Session State but there isn't a simple guide on using this with MySQL. I am getting desperate and considering using a public variable, a string as a replacement to store logged in user id instead of in a session variable. I am pretty sure this will solve my issue with sessions being recycled but are there any negative consequences of doing this? One problem I can think of is if the user closes the browser, the system will never know that the user is now logged out and this public variable should be nothing. In this scenario, will the GC eventually clear this abandoned public variable.
i want to create a arraylist which will able to store user info like (username,machineIP,port ) for each user in the list & retrive this data when needed . any one tell me how i can do it or any alternative way without database or xml file.
I am using a Session Arraylist to hold information about an online user. However, I am having troubel accessing the data. The error seems to be in the last bit because I can access one value of sample data just not print out a number of values. I have an class penalyPoint that has the following constructor:
public PenaltyPoint(string penaltyCode1, string penaltyDate1, string PenaltyPointsAwarded1, string penaltyBan1)
Then in a button response I have the following response which holds the data in a session arraylist variable as the user can enter a number of these objects. I will put a capacity limit on the arraylist later on.
//Assign the data in the form to a PenaltyPoint Object PenaltyPoint penPoint = new PenaltyPoint(ddlPen1Code.SelectedValue, txtPenDate.Text, txtPen1Points.Text, txtPen1Ban.Text); //The current driver number has to be set before this page is called //Temp int currentDriver = 0; //int currentDriver = (int)(Session["currentDriverNum"]); //create an arraylist to be used for transferring arraylist to session ArrayList penPointsDrive0Array = new ArrayList(); if (currentDriver == 0) { //if the session is equal to null then nothing has to be returned from session if (Session["penPointsArrayListDrive0"] == null) { penPointsDrive0Array.Add(penPoint); Session["penPointsArrayListDrive0"] = penPointsDrive0Array; Response.Redirect("PenaltyPoints.aspx"); } else { penPointsDrive0Array = (ArrayList)Session["penPointsArrayListDrive0"]; penPointsDrive0Array.Add(penPoint); Session["penPointsArrayListDrive0"] = penPointsDrive0Array; Response.Redirect("PenaltyPoints.aspx"); } }
Then I try to access the data in the arraylist but I getting nothing printing out. I am just trying to test the data at the minute. I am not that use to arraylist so this might be the problem.
public partial class TestPage : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { ArrayList answer = new ArrayList(); ArrayList driver1 = (ArrayList)Session["penPointsArrayListDrive0"]; PenaltyPoint ps = new PenaltyPoint(); string output; for (int i = 0; i < driver1.Count; i++) { ps = (PenaltyPoint)driver1[i]; string answertemp = ps.getPenaltyCode(); output = answertemp; } } }
I can't get the final part to collect all the values into a string it keeps on coming up with errors.
In my applicaion, I store some values in an ArrayList and store this Arraylist in a session variable. I want to know the size of this session variable in memory. Is there any method to do this.
I am building a web app that is limited to one database, therefore I cannot use the ASP.NET config tool. As a quick means of getting this app online, I tried to use a simple session variable. The login page verifies the user's credentials, and if they pass, it sets the session variable to a certain value. All other pages check in the page_load event whether or not the session variable is equal to that value. The problem is that once being logged in for a short while and sending and recieving some data, the session variable resets, and I'm returned to the login page to repeat the process. Here's the basic code from my webforms:
[code]....
Is there some setting I need to change in the web.config file to adjust the cookie timeout or is that only for the config tool authentication methods?
I added the following code to global.asax to load up several session variable when a session starts. I'm assuming that when a page goes to use the variable that I should be
1) checking at the page level that the value is valid not 0 when its not expected to be 0, not a zero-length string when its expected to have a length
2) have code at the page level that sets the values if the values have not been set as when the Session timeout, ideally putting the code in a class derived from Page and then deriving all of my pages from the new class so that the code does not have to be repeated in every page
I have some code in my page load event where I just want to fire once when the user opens the Browser. The only issue is if you open a new tab with the same website the session variable does not reset. Is there a way to reset the session variable when you open a new tab or do you have to take the whole web browser down for it to clear the session variable.
I'm working on a web page that is going to be used to enter data into a database. The page is going to be dynamic in that the user has the ability to add a row to the table with the same fields, ie lname1, fname1, mi1 then lname2, fname2, mi2
I'm wanting to use a variable to keep track of how many lines there are so that when I generate the added line I am creating a new field with the ID of lname+# . Whats the best way to do this, a global variable, session variable? As side note, first time programming in .Net or C#.
I have been spending a better part of a week trying to track down why I am not able to clear all session variables in a web app (vs 2010, vb.net). What I have tracked it down to is that when I remove or abandon sessions that my html pages or codebehind access, it works, but for some reason in any of my class files where I use "Public Shared strConnection as String = HttpContext.Current.Session("strConnection").ToString" to access a session variable, it finds the old one and not the current one. I have to wait for it to time out, go in again, and it will find the new one.
I do not use Linq, and there is only one place in the whole web app that I place the connection string in a variable whcih is when a person logs in. It points them to the correct database. The sqlconnection is set for all of my listviews in Page_Init to make sure that they aren't using any session variable that they create on their own. Interestingly enough that if I use debug to go in each time, exit debug, enter debug again trying to access a different database, it works correct each time. I assume that debug is correctly killing the session variable for the classes for me.
I am new to asp.net Can you please guide me what is session and session variables ? Please I don't need a comparision of asp session and asp.net session because I don't know anything about asp.

"Now one option if you want to have your DLL pull the stuff from Session is to abstract out session. So you could define an interface like IStorage, that your library will know how to use. Then you can have a SessionStorage or MemoryStorage class and use IoC to inject the appropiate class into your library classes. This gives you the freedom to code it how you wanted it to be coded without tying your code to Session. Oh and one other benefit if done properly can be used to not tie your code to session in the web either.
I am using ASP.NET 2.0I am little bit confuse about using of Session Variable. I have a three page web application. When a user login, after verification of user credentials I get user ID from DB and store this ID in a session variable.Session("USERID") = 56by using this ID I can get 20 different values from database as User Full name, user date of birth, user location, user date of joining, User Commission rate etc. I need some of these values in Page 1, some in page 2 and some values needed in Page 301. After successfully login and getting the User ID, I take all these 20 values from Data Base and store these values in an ArrayList and store this ArrayList in a seesion and whenever I need to use any value I take these values from ArrayList which is save in Session variable.
i am currently storing my shopping cart in a datatable assigned to the session. but i wanted to know is it a good idea to store the GUID for the session shopping cart?
I am building a simple search interface for one of our existing systems. I am using windows authentication. What I would like to do is grab the username of the logged in user via httpcontext.current.user into a session variable on page load and use it in various places on my page. My problem is that when i run my code in debug mode from visual studio it works fine. But when i try to run my code from the browser using localhost it does not work.
I'm building a site (it's amazing how much you can do and still not know what you're doing).I have my visitor login from a login.aspx page and, when authenticated are redirected to a Portal page. On that Portal page at pageload I set a Session variable "UserName" using the User.Identity.Name like this:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If User.Identity.Name <> "" And User.Identity.IsAuthenticated = True Then If Page.IsPostBack = False Then Session("UserName") = User.Identity.Name End If [code]...
