i have two web aplications running on different sites.
1. site gets user information and show another website (2. site) in an i frame. but when i do this 2. site session starts again on every page.postback . if i connect to 2. site without 1. site everything works well.
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 a simple ASP.NET 4 site. I am using Forms Authentication. I have Session timeout set to 20 minutes. Also when the user authenticates I set the AuthenticationTicket to expire in 20 minutes. So normally everything works fine. If there is more than 20 minutes of inactivity and the user requests a page on the site they are redirected back to the Login page as I would expect.
However, let's say that the user is on a page that contains a form. Then they wait 25 minutes. Then they go to submit the form. Instead of being redirected back to the Login page, the site attempts the postback and I immediately get errors because there is code in the postback that attempts to get information out of Session.
It seems like ASP.NET does not redirect back to Login on postback if the AuthenticationTicket and Session has expired. How can I handle this? I hope I don't have to write special code on each page.

I am trying to do a department log in when my page loads, and the problem I have is when someone chooses the department and role from the combo boxes, the first click won't do it. The 2nd click does it. How come? My first click of the button seems to populatethe session but I don't know what's wrong. This is my code:

There is one master page in my application. Left side it display menu and right side there is a Iframe where page will be displayed when user click on menu. so entire page will not be refreshed only Iframe will be refreshed.
Everything is working fine for me but I am facing problem when session expire, my loginUrl page display inside Iframe so user is able to see left menu.
I am thinkin that LoginPage should be display in main screen instead of Iframe.
My web.config is as below.
<authentication mode="Forms">
<forms loginUrl="Login.aspx" defaultUrl="Default.aspx" protection="All"></forms>
</authentication>
I have a background set of images that is called randomly.It changes each time a user opens a new page and refreshes the same page.Not 100% of what I want.
Ideally I would like a random image to be shown each time a user comes to the site but not on every page.
Is there a way to set the image per the session a users visits the site instead of each page?

I have a very interesting problem about Sessions and Master Pages. I designed a small CRM web application with master page. Users could enter their expenses with this application. I put a label on master page. If users login to this site, I changed this label text.
Label text is username. My problem is; when some users using this site at same time, usernames are conflict. For example; One client login and label which on the masterpage value is Ali. Another client login and label value is Ahmet. After that, If two clients process the same things on this site, Ahmet's label's value is changed to the value of Ali. I write it Session Id on URL. Firstly two clients take different Session ID when login to that page. When conflict occurs, two clients are the same Session Id that pages. I am using .NET Framework 3.5V. Is this ASP.NET bug ?
I have a button that executes a script using AJAX.Normally when a session is still active the script will return some data that will be placed inside the parent page.If the session expired the AJAX will return the login screen which gets placed inside the parent page which looks really odd.How would I be able to detect a session timeout and do a postback on the parent page?
View 2 RepliesI have a ascx page on load of the page I save few data in the HttpContext Session, on selection of data in the screen I reload the page with relevant data for the selection. Until here the data in the session exists. But on click of a button say ok button to navigate to next page. all the data in the session is lost. But the same works in windows 7 and windows server 2008 not in windows XP. are there any configuration difference in windows 7 and XP.

I check IIS, session time out time is 60 minutes.
Is there any way to set a session from an IFrame?
Here is my issue...
My client has an asp.net website that opens a php web page inside an iframe. When the user accesses that page there is a "login" from the php site that shows up. The user logs in and can view that page from the PhP site.
All I need to do is set a session on the asp.net website that lets me determine if the user has logged in. Any way to tell me .net site that the user successfully logged in via the iframe page?
Session("LoggedIn") = "True"???
I have session variable that is created in EditPlaylist.aspx. Edit.aspx is loading EditPlaylist.aspx in an iframe. when loading sessions from EditPlaylist.aspx page they are null. the session was not before I added the EditPlaylist.aspx to an iFrame. Is there a workaround for this?
View 1 RepliesI have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)
I have a "one page application" (ASP.NET 3.5, VS 2008, IE7) that uses Default.aspx as it's page, and holds an iFrame within "floating panel" (asp:Panel with extenders).
As the desired behavior is to allow users to reopen the application by refreshing the page,
I added this to the Default.aspx.cs:
protected override void OnPreInit(EventArgs e)
{
if (!IsCallback && !IsPostBack)
{
Session.RemoveAll();
GeoApplication.DAL pDAL = new GeoApplication.DAL();
Session["DALinstance"] = pDAL;
}
}
However, when the iFrame page lifecycle starts, the Session["DALinstance"] parameter is null. I've tried to put some additional parameters and those were null as well.
I have session variable that is created in EditPlaylist.aspx. Edit.aspx is loading EditPlaylist.aspx in an iframe.

I'm a bit stumped by this one. Have a VS 2008 website running on Windows 7 using the VS web server. One of the pages transfers to another page (page2). On page2, each time I cause a postback by clicking a button, I get a different session.sessionid. I was under the impression sessionid was constant throughout the session, i.e. until the browser is closed or the session expires (~20 minutes). Is this just a VS web server quirk?

View 1 RepliesWe're using ASP.NET and IIS 6.0. I realise that the definitions of applications, websites and virtual directories are ill-defined in IIS 6, and changed a lot in IIS 7. However, I'm stuck with IIS 6.0 for now.
We have a single web site defined in IIS, and a number of separate sub-sites in Virtual Directories.
The scheme looks like this:-
[URL]
[URL]
site1, site2, ... are virtual directories in IIS 6.0, under the "Default Web Site".
I need to use ASP.NET sessions and forms authentication in most of these sites, and I don't want them to share authentication data or session information at all.
Both the mechanisms currently depend on cookies. However, the cookies created by default use the same name, and have a path of "/" in the browser, meaning the sites' cookies will clash with each other.
Without changing the default name for each cookie, how can I enforce separation between my sub-sites? Do I need to change the virtual directories for IIS 6 "Applications"? Or is there some way in code to enforce a more limited scope for the cookies?

I have been using session variables in my asp.net application for passing the next property:
[DefaultValue(true)]
public bool IsModificationMode
{
get
{
return (bool)Session["ModificationMode"];
}
set { Session["ModificationMode"] = value; }
}
In the PageLoad, I set it's value.
Now after the Postback, I am losing it's value having a a NullReferenceException
