Web Forms :: Page Expiring After Some Time?

May 1, 2012

I am working on Visual Studio.Net 2008  framework 3.5  with (vb).

I have created a session variable, when user logs in successfully. But after login if page kept ideal for sometime session get expired, and automatically redirects to login page.

 So, I want that after login page should remain  opened and session would never get expired until user clicks on Sign out link or button.

For this do i have to set anything in web.config file?

Cache Is Not Expiring

Sep 12, 2011

I have this code:

protected void Button3_Click(object sender, EventArgs e)
{
DataView dv2 = (System.Data.DataView)Cache["SqlSource"];
if (dv2 == null)
{
SqlConnection con = new

[Code] ....

For some reason, the Cache is not expiring. What is wrong with this code? I am aware that I could do this using the SqlDataSource1.SqlCacheDependency property, but I'd like to know how to do it using the SqlCacheDependency object.

VS 2008 - No Expiring Or No Cache

Jan 11, 2013

I have 2 issues, the fix to one issue gives me the other issue.

In simple terms I have an asp page that uses ajax to get its data. I do not want to cache this page as the data is out of date if you re-open it. The page has buttons to allow the user to do stuff, such as change the view, so when pressed the page that comes back is the result of a POST.

The page also has links to external websites, this is what happens:

User opens webpage
User clicks a button to change view POST
User clicks a link to external website
User presses Back button which then flags up the "Webpage expired" type messsage because the results are from a POST (I believe)

To get around this I was caching the page, this then leads to another problem, the cached page being out of date (in fact I use external web-parts which show as white blocks as they are NOT cached!).If I wait long enough, the ajax kicks in and the data comes back.

So, I can't cache it without getting a huge delay before being able to see anything, and I have to cache it to get around the POST/expired type issue.

C# - How To Prevent The Session From Expiring While Using AJAX

Sep 17, 2010

I have a .Net 3.5 website which uses windows authentication and expires the session using a meta tag on the prerender of my base masterpage class.

protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
if (Response.ContentType == "text/html")
this.Page.Header.Controls.Add(new LiteralControl(
String.Format("<meta http-equiv='refresh' content='{0};url={1}'>",
SessionLengthMinutes * 60, SessionExpireDestinationUrl)));
}

This works well for pages that do full post backs. However there are a few pages in my application where the user does a lot of work that is inside of an update panel. My company's policy is a timeout of 15 minutes. Which means, after 15 minutes of working inside of an update panel page, the user gets redirected to the application splash page.

Is there a way to reset or extend the meta tag on an async postback? Or perhaps a better way to accomplish this entirely?

C# - How To Write The Code For Self Expiring Download Link For Website

Jul 19, 2010

I am planning to sell digital goods on my website (Asp.net). After successful payment the customer will be redirected to the download page of my website, which will display the link to download the digital content stored in my server.

I want to secure the location of the file, by creating a disposable link to the file. Every time a customer visits this page a new download link will be generated for the same file. Also this link should expire after it is downloaded for the first time.

Is it possible to do it in asp.net ( C# preferably )? if yes how can i do it?

VS 2008 Registration Form - Creating Expiring Cache

Sep 27, 2011

So I'm attempting to limit user's access to my database through the web. I have a registration form that asks the user for a name and password, then verifies this against a DB. In order to prevent DB overload, I will limit the user's attempts to 10 in 10 minutes. This is how I am trying to solve this, but cannot verify that i'm using the right approach.

Code:
Dim timeout As Integer = ConfigurationManager.AppSettings("timeout")
Dim userIPkey As String = Me.Context.Request.ServerVariables("REMOTE_ADDR")
Dim i As Integer
If HttpContext.Current.Cache(userIPkey) = Nothing Then
i = 1

[Code] .....

For some reason I can hit the service with a for loop and get to the DB every time. If I try doing this through the browser while debugging the webpage, I get the right error message after 10 attempts, while on the server, or through a reference to localhost I will not get the error message.

Page_Load Events Executed Every Time A Page Was Loaded Not Just The First Time?

Aug 5, 2010

I thought that Page_Load events executed every time a page was loaded not just the first time. Am I wrong on this?

I have a Page_Load event that writes text to a label to display on the screen: Output.Text &= "Welcome to my Website <br />" (Output being the ID of a Label control)

I also have an On_Click event for a button to display the same information: Output.Text &= "Welcome to my Website <br />"

After clicking the button, I expected to see the output twice. Once for the page being reloaded and once for the click event. I thought that Page_Load events executed every time a page was loaded not just the first time.

Visual Studio 2010 - Site Upgraded VS08 - VS10, And Now Compile-time Errors Do Not Show Until I Request The Page At Run-time?

Mar 11, 2011

I have an ASP.NET website that worked fine using and debugging in VS2008. I went through the upgrade process opening the solution in VS2010. I can run the site, but as I make changes in the app_code folder classes, they don't seem to commpile and warn me of compile-time errors. As soon as I get to a point that calls the class, the errors show up. Sounds JIT I guess, but this isn't how it was working in 08. Is there an option that was changed in the upgrade process? This is a large project, I really don't want to break something and not find out until some obscure page is opened.

Forms Data Controls :: 11 Gridviews On Same Page - Optimize Page Load Time?

Oct 4, 2010

I have a web page which has about 11 gridviews.Hence the page takes bout 15 seconds to load.The grids are 1 below the other.They are populated at the page load.

I need a solution to reduce page load time. Is there a way,where the gridview loads only if user scrolls to it. I donot want the user to make selection for everytime he wishes to see a gridview. The page should show gridview if its data is bound to it, not waiting for entire page gridviews to get populated.

Forms Data Controls :: Time Used As "amount Of Time Available", Not Time On A Clock?

Jul 6, 2010

how to suppress the "AM" in the gridview (template Bind("RideTimeMin", "{0:t}")? Don't tell me to use military time because the function is not "time on a clock"; it's how much time is allowed for a task (in this case the min/max hours & minutes that horses have to complete a 20 mile trail; e.g. 05:00, 05:27, etc). I'm currently accomplishing this in the "ondatabound" function by "..RTmin.Replace("AM","")". I have looked and looked at all the websites that talk about datetime formatting but have yet to find a way to do it upfront in the gridview bind statement.

Web Forms :: Count The Loading Time For Page?

Jul 14, 2010

I recently re-develop our company's web system. However, when I just finished everything, our internal user complains that the page is noticable slower than the old one. I tested it on my machine and it seems to be ok. As it is a major concern of my manager, I decide to add a bit of code to return the time comsumed in page loading. Can someone give some idea about it? What I try to know is: from the time user click on "submit" button until the page is fully loaded to the user, how many seconds it costs. I have ajax in the page. Is it possible to do it in js? or any other sort of way is fine too.
