I've some doubts on sessions in asp.net. If the client send a first request to a website then in response the site sends a sessionId which will be stored in browser as a sessioncookie upto this point its clear for me. If the same client sends the second request the session ID should send to the server to idetify the user.my question is How this will be send to the server?
second question: why not the session_End event won't get fired if the session mode is OUTProc??if i want to execute some code when session ends where can i put that code??

"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.
the following web.config file is placed in a specific sub-folder on a website. It will allow the user John.Doe to access the pages inside the folder but will deny anonymous users
Is it possible to replace users in the following web.config file with certain session variable for example getting the day(sunday, monday, etc) from date and storing it in session("DayVar")
then the code should be something like this for the subfolder monday
I am have declared a session variable in login page of my application. I want to access that session variable in Application_BeginRequest of global.asax file. But I am not able to do it. Could you please suggest how to access the session variable in my global.asax file
Currently in an .aspx file, I am storing a value (filename that was created in that session) in an hidden text box. When the user clicks on the "Print" labeled Hyperlink control, it opens the file that was stored in the hidden text box control. But when the user goes to different screen (in the same session), I loose the filename value that is stored in the hidden text box control. So I would like to store the filename variable in a session variable. So that if the user leaves this .aspx file and comes back to this .aspx file I can load the value into the hidden text box from the session variable.
I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />
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.
What would be the proper syntax in ASP.NEt 3.5 C# to assign a TextBox value to a temporary or session variable to be manipulated (added, subtracted, multiplied, divided) at different points in the application? I want to add a decimal number to this variable in almost every instance as well.
I have the dataset. in this i am having total 20 tables with huge amount of data..I want use this data over all the page..so where i can keep this data..
before i used viewstate but the viewstate data is render to page every postback ..so this time the page size is increasing(interanlly viewstate is rendered to page)..so performence wise it was very slow..
Now i change my logic insted of viewstate to i used Globel Dataset on Page Level.. now the performence wise better than viewstate..
i used Like shared dsControls as Dataset at top of the page..so every time i use this dataset..
my quesation is session is better or Globel variable is better way use in my situavation..
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 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 have some cascading dropdownlists using the ajax toolkit I have a set up datatables in an xsd file. Then use these in a webservice to populate all the fields ... this all works great but now i need to pass an additional paramter to the first dropdownlist ( a date) but don't know how to do this? The method is below...
[Code]....
The other code is:
[Code]....
The first change would be to the tableadapter to add a param to the code i.e
AuditWebDS.TeamsDataTable teams = teamsAdapter.GetTeams(calldate);
but how do i get the calldate param to the webservice method... i tried a session variable but it comes up with session is null ? Is there another better way?
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. I have saw many articles on types of session as well. But still I cant understand exectly what is session and what are session variables in asp.net ?
I'm working on converting the TailspinSpyworks shopping cart Joe Stagner wrote in C# to VB using an evaluation version of VS 2010. I have the following public function:
Public Function GetShoppingCartId() As [String] If Session(CartId) Is Nothing Then Session(CartId) = If(System.Web.HttpContext.Current.Request.IsAuthenticated, User.Identity.Name, Guid.NewGuid().ToString()) End If Return Session(CartId).ToString() End Function
For Session in Session(CartId) I'm etting the following error: 'Session' is not declared. It may be inaccessible due to its protection level. For User in User.Identity.Name I'm getting the same error: 'User' is not declared. It may be inaccessible due to its protection level
I am using Httphandler to access my pages. Have Loginstatus Control on the master pages.
OnLoggingOut for the Loginstatus control I am doing a Session.abandon()... But My session_end
does not get called in the Gobal.asax.I tried link button and everything. but when I take out the httphandler the Session_end gets executed in global.asax
I can handle the full session end on my own but is there any way to call Session_end in global.asax?
I'm creating web application behind load balancer. To this moment I configured it to store session in database but I'm not sure how should I handle session expiration. The problem is not sessions are not removed from database but Session_End event because I have to call some web service method in it.
Assuming Session_End is called when expires the thing I'm afraid of is situation when session is created on one server but finished on another. In this case I'm afraid Session_End on first server will be executed prematurely and I will call web service too early. What would you suggest in this situation?
Edit:
I remember some time ago reading about Sql Agent reacting to session end event and then performing custom code. Can anybody confirm that this solution is possible?
