As we know that closing a browser will delete cookie if the cookie does not set an expired date. However, I want to set an expired date to all of my cookies and also delete them when browser closed.
View 2 RepliesI receive the error message "Error: Your session has expired. Please refresh your browser." When I export a table in ASP to Excel. I know for a fact that the correct data to export exists. Everything works fine except for this error message. I don't see how the session on a browser could run out in a matter of the one second it takes for the Excel file to pop up
View 2 RepliesHow to keep the session variables even after closing the browser?
Everytime I close the browser, I lose all the session variables.
Is there any way to keep them?
writing code for Session_Start() and Session_End() such that whenever a user closes the browser without logging out he is automatically forcely logged out......And too when a user logs out normally he is re-directed to the LogOn page....

View 2 RepliesI am using the following code to ensure that the web pages in my website are not cached by the browser:
this.Response.Expires = 0;
this.Response.AppendHeader("Pragma", "no-cache");
this.Response.Cache.SetNoStore();
This is working fine & the browser displays a page with the message, "Warning. This page has expired....". Is there any way I can display a custom page instead of the default page shown by the browser?
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 in dot net i create a website. and managed session variable to stored logged-in user information.when someone close the browser, session still exit or db not update.

View 1 RepliesI'm using the code below in the we.config file.
<sessionState mode="InProc" cookieless="false" timeout="30"/>
There is no issue with the session expiration locally, but the same web application logouts frequently when I uploaded it to the webserver. The session no longer keep it's state for 30 minutes when the application left idle for some time.
now i need to test on a website, which i able to login to the main website and some of the sub-website or sub page. but when i click on 1 of the link to link to the page. it always show me Timeout expired.
I already try to restart the IIS admin service and make sure my database is up and connected.
now i test on my development server. so the website i browse is at localhost.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
The error i get as below. hopefully get some idea to solve this issue.

when i run my web application in my system the session not expired during access of the pages, but when i launch application in the remote server the session expired during access of the pages
i specifiy the session time out in web.config as follows
<sessionState mode="InProc" cookieless="false" timeout="30" />
But i don't know what the problem is
it is having the grid with bulk of data. So i decided to move to Cache to strore the dataset. So that it avoids in gettin the data from DB for each time the page is loading. Suppose my idea isnot good please suggest me the best way to acheive this.My question is if i suppose store the data into the cache, how can i dispose or clear the cache from the memmory for each time i close my current page or application. I dont want the cache in memmory for long time, i want only upto the time the application is running.
View 6 Replieshow to create cookies in asp.net . and how to access them ?
View 6 Repliesi 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.
In my website I am maintaining cookies for the login so that if I open the browser again then no need to login again.
But when I am switching browser(from ie to ff or viceversa) then the cookies are lost and the user is not identified, I want to maintain them in this scenario also.

I'm working in vb language and I would like to know how to store the values of asp.net controls (textboxes, selected items of combo boxes etc) so that I will be able to display them on a different page. I was using cookies but it's not working.

Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Response.Cookies("FirstName").Value = txtFirstName.Text.ToString()
Response.cookies("Date").value = cboDate.selectedItem.Text.ToString()
Response.Cookies("FirstName").Expires = DateTime.Now.AddDays(1)
Response.Cookies("Date").Expires = DateTime.Now.AddDays(1)

code for read write cookies in asp.net?
View 1 RepliesI tried to set a Cookies by Response.Chookies("chookie1") into a user's machine and found difficult to get the Cookies by Request.Chookies("chookie1"). I think that is because the person used various cs(User-Agent) (browser names?). Here are some of them:
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1)
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+CLR+1.1.4322)
Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+InfoPath.1
In such case, how can I set Cookies to identify that machine?
I am developing questionare web site, where user has to answer around 55 questions. Its basically a check / uncheck option. So when user submit I store the value in DB.
The issue I am facing is if user selectes all the option, cookie value is lost. I see only 50 records can be stored (Request.Cookies.AllKeys)
Even the SessionID value is lost.Any solution / work around.
I need to store in the client side only. because if the user choose all options and do not submit. The values can be stored in the cookie and later point if he comes back we can read and give to him
ASP.NET / C#
We are facing a very strange issue, which is senseless. We have dedicated test server and live server. cookies work properly both on IE and firefox locally. when we deploy it on dedicated test server, It also work their on both browsers. But as soon we deploy it to our live dedicated server, it works properly on IE, but firefox does not remember cookies. Here i want to tell you one more thing that both test setver and live server configurations are same. they both are 64 bit machines. Waiting for ur responses.
View 3 RepliesCan someone show me what I need to do to allow cookies:
I have this code after I "authenticate" the user (my own Login Control, & code to authenticate).
If the user checks the "Remember Me" checkbox I am trying to set a cookie with this:
// add 1 month
DateTime expireDate = currentDate.AddMonths(1);
// set the cookie
HttpCookie cookie = new
HttpCookie("LithoUserName");
cookie.Value = customer.UserName;
cookie.Expires = expireDate;
cookie.Domain = "lithoman.com";
Response.Cookies.Add(cookie);
When I go to retrieve the cookie the value is not there. It worked once, then I closed the browser and it disappeared (the cookie was no longer there).I went to GMail & there cookie worked so I am pretty sure the problem is my web.config, but most of the examples for Forms Authentication want you to "authenticate" with Forms Authentication, all I need is for cookies to work. I was able to do this real easy 12 years ago in Class Asp using Visual Interdev, & thought that product sucked compared to Visual Studio 2008 today, but if progress makes a cookie not work then something is wrong. This is not a bank site, or a matter of a life or death, it is just a time saver to sign someone in.
