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 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.

Am trying to design login page for my website and I am looking for methods other than forms authentication. The way in which I am trying is to have a table in the database that stores user information and check for the user validity.
The point where I get struck is how do i set cookies and session variables and how will I carry it through out the system. Can anyone tell/suggest me where I can relevant material so as to move forward. And also is my idea of negating traditional forms authentication and going for a model I described, is it good also does any other better method exist?

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..

my main concern is using Session. I've always been under the impression that if you use the following statements (not that I would):
Session["newVar1"] = "a new session variable";
Session["newVar2"] = "a new session variable";
Session["newVar3"] = aLargeVariableThatHoldsLotsOfData;
You would be creating 3 new session cookies that hold the particular value. But I think my asp book is indicating that you would actually create 3 new variables in your session state object and ASP would only pass a unique Session ID (as a cookie?) in the response, and would get this ID upon the next request and associate that ID with your Session State Object (that IIS has stored in memory..?):
[code]....
That doesn't seem ideal for a website with lots of traffic. A server that is storing and maintaining thousands and thousands of instances of session state per website seems like way too much overload.
I'm trying to see what's going on on my own, but I'm having trouble.. I can't find my site's cookies anywhere on my machine (IE/windows xp). I've checked C:Documents and Settings icholasrCookies and C:Documents and Settings icholasrLocal SettingsTemporary Internet Files which, according to this yahoo answer, IE cookies are stored as well. I'm using ticket authentication in my app which stores a auth cookie on the client, so a cookie from my site has to be somewhere..

So, I am working on a demo web dashboard. Previously, I had been using Session to store settings about the dashboard, but I would like to move it to a more persistent means of saving settings.It seems to me that using cookies would be my best bet. I'm not entirely positive I have the time to work everything out for writing to/from a database properly.That being said, I might be in over my head on some assumptions I had made about the similarities between Session and Cookies. Currently, I have some code like this:
public Dictionary<string, RadPageViewSetting> PageViewStates
{
get

i have 3 pages, lets say pageA, pageB and pageC.
1 . From "pageB", i'm sending some data to "pageA" and and retriving the result with using HTTPWebRequest and HTTPWebResponse classes. I have no problem with this
2. pageA fills some session data, like Session["CustomerInfo"] .
3. After retrving some data from "pageA", I'm redirecting from "pageB" to "pageC".
At PageC, i want to use session variables which i fill at "pageA":
At pageB, i get the CookieContainer of the HTTPWebRequest object and it retrives correct SessionId.
And here is the code that redirects pageB to pageC:
Response.Cookies.Clear();
Request.Cookies.Clear();
foreach (Cookie cookie in SessionCookieContainer.GetCookies(new Uri(http://localhost/bla/bla)))
{
Response.Cookies.Add(new HttpCookie(cookie.Name, cookie.Value));
Request.Cookies.Add(new HttpCookie(cookie.Name, cookie.Value));
}
//Response.Redirect("../Default.aspx");
Server.Transfer("../Default.aspx",true);
At pageC , Request.Cookies and Response.Cookies are set truly, as i sent them from pageB, but there is nothing in the session. Session.Count is zero. And SessionId is different from the value which is stored in cookies.

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.
In Global Page:

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 having this weird problem only when i deploy my site [localy Everything works fine] when you try loging in from IE 8, the page simple refreshes! and no authentication takes place After lot of research, i found out that Internet Explorer 8 denies session cookies and to confirm this, i unchecked Enable protected mode (can be found in, internet options, security), and then tried logging in, it worked perfectly fine just like it did in other browsers [Firefox and google chrome]. I have found one solution which is to lower the security level, but i cant tell every visitor on my site to do that since its not practical.

I need to persist data between pages.I tried using session but the value is not saving.
Should using cookies be a better option? If so give a small example of transfreing and saving data between pages.

It has been a while since I've built an entire ASP.NET web application from the ground up but I'm about to jump in again. I've built many individual pages, controls, web parts, etc. recently, but nothting 'soup to nuts' for a couple of years. My question is in regards to login security control. I do not want to use the built in ASP.NET Memberhip functionality for various reasons and already have custom code that authenticates the user, controls passwords, login attempts, etc. I am really concerned though about how to validate that the user is logged in (and the best way to do it). For instance, right now I use a Base page that all of my .aspx pages inherit from. In the OnInit() method, it executes code which includes:
[Code]....
I set the Session["LoggedIn"] object to "true" after the user has successfully been authenticated at the Login.aspx page. So, when a user attempts to access any page in the application, if that Session object isn't true, they will be redirected (you can't visit any page without being logged in). This all works great, but I'm thinking I need something more and that brings me here. First, do I need more? Is this enough? I was thinking about creating a cookie with a GUID value and the SessionID (both encrypted perhaps?) and adding that to my Base page so it checks both the current Session["LoggedIn"] value
and the values in the cookie.

I am using "cookies" to maintain session in my asp.net azure application.
What I want is that when a user logs in to my website and remains idle for 15 minutes it should automatically log them out and redirect them to the login page.
How can I achieve this?
