I have been asked to work of a very large web application and deploy it. The problem that I'm facing here is that when I deploy the application and more that 1 user logs into the system, the sessions seem to cross over i.e: Person A logs in and works on the site, all good. When person B logs in, person A will then be logged in as person B as well.

If anyone has experienced this behaviour before and can steer me in the right direction, that would be first prize, Second prize would be to show me how I can debug this situation so that I can find out where the problem is and fix it.Some information about the application. From what I've been told and what I've seen within the app is that it started as a .Net 1.1 application and got upgraded to .Net 2 and that's why the log in system was done the way it is. (The application is huge and now complete and that's why I cant rewrite the whole user authentication process, it will just take to long and I don't know what effect it might have)
All the Logged in User information is stored in properties that have been added in the Global.asax.vb file. (could this be the problem?)
I want to debug EditPanel.debug.js file of HTML Editor, but it never shows in VS 08 and Im sure it executes to that line.What I did to enable debuggingUnchecked both 2 checkboxes for disabling the debugging
Set ScriptMode="Debug"
Change following line
[ClientScriptResource("AjaxControlToolkit.HTMLEditor.EditPanel", "AjaxControlToolkit.HTMLEditor.EditPanel.js")] to [ClientScriptResource("AjaxControlToolkit.HTMLEditor.EditPanel", "AjaxControlToolkit.HTMLEditor.EditPanel.debug.js")]
I have an ASP.NET web application that takes user input across several forms. Sort of like a wizard. On the first form, the user enters information then clicks the "Next" button. In the Click event of the button I save some information to the Session object (via Properties in the Master page). I then Redirect to the next page. Here is an example of what I am doing:
protected void NextButton_Click(Object sender, EventArgs args) { //Go to the next form Master.SessionVal1 = Value1; Master.SessionVal2 = Value2; Response.Redirect("~/TheNextPage.aspx", false); }
In the MasterPage.cs..
public long Value1 { get { return (long)Session["Value1"]; } set { Session["Value1"] = value; } }
public long Value2 { get { return (long)Session["Value2"]; } set { Session["Value2"] = value; } }
Pretty basic stuff. When I run this in debug mode in VS2008 it works perfectly. When I push this to a test server (IIS7) I get NullReference exceptions when I try to access Value1, Value2, etc. which is stored in the Session object. UPDATE: I have discovered that if I migrate the code to one server I get the problem as described above. BUT, if I promote to another server it works as expected. Both servers are Windows Server 2008 with IIS7. I have looked at the application pool settings and the state management settings and I do not see any differences.
I am trying to pass a key value from one page to another, using VB.net and Visual Studio 2008 Professional. I am creating a session variable in one aspx page and trying to retrive the value in the second aspx page (Dircted to by a button with the postbackurl set) However, the session object is empty when I try to access it in the second page. If, however, i put a debug hold on the code which retrieves the variable, and examine the session object from the "locals" debug window, i see contents. When I then resume the application the code retrieves the value correctly. I am executing my code using the development server that comes with Visual Studio. Could it have something to do with that?
Debug-Start Debugging/Debug-StartWithoutDebugging OR Project ASP.Net Configuration launches Dreamweaver. It started lastnight, I had both Deamweaver and VWD 2008 express open at the same time - (I was looking at JQuery in the Microsoft and Dreamweaver enviroments simultaniously). After the first tie this happened, I closed down Dreamweaver (CS3) and it opened when I tried to run my VWD project. I reinstalled VWD 2008 express, IIS and disabled Dreamweaver (renamed the exe). Dreamweaver still came up.
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 want the code for showing popup dialog box , to show the time remaining for session closing because of in-activity. and 2 buttons for allowing to stay or to signout.
i want all the settings that are need to achieve the functionality.
can i register a debug logger that outputs information to the 'standard ASP.NET debug window'. My problem is I don't know what that means, if it means the debug output window in Visual Studio (where you see build output, debug output and more) I am not seeing any UrlRewriter debug output. The rules are working (mostly) I just want to get more debug output to fix issues. I added the register call to the rewriter section like this:
I have an ASP.NET C# project consuming webservices and WebMethods are wrote in VB.NET with source code on a local IIS server. The WebMethod returns null, and I want to debug it to know why I get this.
if I set a breakpoint just before the webmethod call, I cant step into this webmethod.
So, how is the correct way to debug this webmethod?
I have a class called EditMapUtilities. Here are some class properties that I want to persist:
public class EditMapUtlities { public static Boolean isInitialEditMapPageLoad { get { return SessionHandler.isInitialEditMapPageLoad; } set { SessionHandler.isInitialEditMapPageLoad = value; } } // REST OF CLASS NOT GERMAIN TO DISCUSSION AND OMITTED }
Here is my SessionHandler Class following the pattern from this post Static Session Class and Multiple Users: using System.Web.SessionState;
public static class SessionHandler { private static HttpSessionState currentSession { get { if (HttpContext.Current.Session == null) throw new Exception("Session is not available in the current context."); else return HttpContext.Current.Session; } } //A boolean type session variable private static string _isInitialEditMapPageLoad = "EditMapInitialPageLoad"; public static bool isInitialEditMapPageLoad { get { if (currentSession[_isInitialEditMapPageLoad] == null) return true; else return (Boolean)currentSession[_isInitialEditMapPageLoad]; } set { currentSession[_isInitialEditMapPageLoad] = value; } } }
I am still learning OOAD. I want to keep relevant properties with relevant classes. I also want to keep all Session stored variables in one place for ease of maintenance and to encapsulate the session keys and calls. I feel like my design is too coupled though. How can I make it more loosely coupled? Is my editMapUtilities class too tightly coupled to the SessionHandler class? How would you do it better?
Let suppose, I am building an asp.net website which has login scenario in it. I want to provide a certain functionality to the website that if the user is already login on computer 1 and now try to login on computer 2, so he will be allowed to remain login on computer 2, while automatically logout him from computer 1. I also know that http is a stateless medium, so whenever user interact with computer 1 and try to interact with the page, it will get noticed at that time.
Is there room for issue in the following code in terms of multiple users of the same web application? I mean, I know that a purely static string will be shared across all sessions for a single ASP.NET application, but since this explicitly refers to the Current.Session, even though it is static it seems like it would always refer to the session instance of the "current user." But an error is happening that could be explained by everyone sharing the current value of Mode and thus the most recent change overwriting everyone else's mode value. (As a background: This string is in a Helpers class that is used throughout the application. I do not want to make references to Session["Mode"] throughout the application and do not want to have to pass Session["Mode"] in every method call from an aspx.cs page.)
public static string Mode { get { var value = HttpContext.Current.Session["Mode"]; return (value ?? string.Empty).ToString(); } set { HttpContext.Current.Session["Mode"] = value; } }
I use some session variables to get the job done(shopping cart, etc) but it is not stable..manytimes I get no items in session object and other times(refreshing the page) I get missing data...I downloaded the entire site code to my local pc and debugged it and run it succesfully without any session data missing...When I run it in the server, I get bad session again: no products in shopping cart or products with missing quantities...
The same website runs smoothly in our production server too....The problem is with our development server...
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 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 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.
There are two pages in my app, A and B.A is login page from which user ID was saved in a session. Once user login, B is open and user ID will display in B. When user submitted an order successfully at page B, page B will reopen but user ID was missed. How to fix it to keep session value in 20 minutes as default? I check IIS, session time out time is 60 minutes.
I need to make my asp.net session cookie as secure but whenever i check user authentication and after that i am trying to set cookie to true then my session lost my user information and so it always redirect login page. I am settings user to HttpContext.Current.Session["user"] and check every time, is user is valid and if valid then move ahead. but before that i make my asp.net session cookie as true.
[Code]....
but after that i observe that somehow "Session_Start" event gets called.
