(i) I have a simple application where I am getting data from a textbox and storing it in a cookie. I noticed that unless I set the Autopostback value of the textbox to TRUE, nothing is stored. Does anyone know why this is the case?
The code I am using are as follows:
[Code]....
I'm using the following line of code to display the number of users currently logged on:
lblNoOfUsers.Text = Membership.GetNumberOfUsersOnline().ToString()
I'm still debugging my application so it's on the local server. As I debug and stop then debug again, eventually lblNoOfUsers.text turns to "0" instead of "1", even as I'm navigating my application. It only turns to "1" again if I log out and sign back in. It's almost as though Membership.GetNumberOfUsersOnline my login are referencing two different session states. How is this possible? Does asp.net create a new session state cookie each time I start debugging?
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.
We have a local homepage, which connect to our production security environment. When I need to test my site in test environment, I need to get fresh cookie (not the one that was sent to me via production security service, when I opened IE with local homepage).
I am getting fresh cookie fine in Mozilla; but in IE I always have production cookie, and this disables my testing. What I should fix here?
I would like to change ASP.NET session cookie name "ASP.NET_Sessionid" to some other name. I specified <sessionState cookieName="MyCookieName" />. When I use fiddler to view response header, I can see "MyCookieName" with random generated number under cookie section, however, ASP.NET_SessionId also exist there.
View 2 RepliesI 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.
I have a website for a simple game. When people sign in their Player ID is stored in a Session variable. I have integrated SMS payments so that my players can buy credits to use to play. This is where the problems start:
To buy credits, players are presented with an .aspx page that holds an IFRAME of the SMS payment proviers form. A code is entered, and the IFRAME POSTS to a URL on the providers server. It is then redirected back to an URL on my server(www.XXX.com/process.aspx), where I handle the results (i.e adds credits to th players account if the payment was successfull).
However, the session dies on return.
I tried with cookies, and saves the player ID in a cookie, but when upon return to www.XXX.com/process.aspx I cannot read the cookie? I'm checking for if (cookie == null) and it evaluates to TRUE, so the player is redirected to an error page.
How come the cookie cant be read? Is it because the POST is coming from an outside URL? And, what about when I do it with a session variable? Same thing there?
If I have two "webroles" (azure), that are NOT using a shared custom state provider, is the "Session.SessionID" be the same in both?It would make sense ,considering that both get the same cookie (because are in the same domain) and have the same machineKey, but I'm not sure
View 3 RepliesWe have a web app running .net 1.1 that users must login to access (uses FormsAuthentication). At one point, the user submits a form that is handled by a separate web app on the same website but in a different directory (running .net 2.0 and not requiring authentication). When the user submits the form and is redirected to this other page they have some options including returning to the previous web app.
We need our users to stay logged in to the first web app so they do not have to log in again when returning. This works fine on 3 out of four computers, but the fourth computer is asked to log in when they hit the return button (by reviewing the active cookies we see that when it returns to the original web app, the FormsAuthentication cookie is missing)
why this cookie would disappear on one machine but not the others? I am going through IE settings now but the machine has the problem in IE and Chrome (not sure if this would be a shared setting) If it is an IE setting is there a way to make this work without requiring the user to change their settings and without switching to cookieless sessions?
Here is the authentication part of web.config

And if it makes a difference, the redirect and form action property use a the full path, would using a relative path likely change anything?
I searched on this all morning, but I'm still not sure. If I create a session variable to pass some data between a couple of pages, does that variable time out after it reaches the timeout period set on IIS, or will it persist for the entire time the user keeps a session alive? For example, session variable is used shortly after login and then never again. Susy uses other pages for two hours and keeps session active. Did that first session variable die after 20 minutes, or is it still there 2 hours later?

basically am using them to store user id and status, so that pages can be validated, by there use.i can stop person from accessing home directly wihtout signing is and so on.can session variable be hacked as they are stored in an external data source and are available to the full website?
I am building a web app that is limited to one database, therefore I cannot use the ASP.NET config tool. As a quick means of getting this app online, I tried to use a simple session variable. The login page verifies the user's credentials, and if they pass, it sets the session variable to a certain value. All other pages check in the page_load event whether or not the session variable is equal to that value. The problem is that once being logged in for a short while and sending and recieving some data, the session variable resets, and I'm returned to the login page to repeat the process. Here's the basic code from my webforms:

Is there some setting I need to change in the web.config file to adjust the cookie timeout or is that only for the config tool authentication methods?
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.

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 to asp.net Can you please guide me what is session and session variables ? Please I don't need a comparision of asp session and asp.net session because I don't know anything about asp. I have saw many articles on types of session as well. But still I cant understand exectly what is session and what are session variables in asp.net ?

"Now one option if you want to have your DLL pull the stuff from Session is to abstract out session. So you could define an interface like IStorage, that your library will know how to use. Then you can have a SessionStorage or MemoryStorage class and use IoC to inject the appropiate class into your library classes. This gives you the freedom to code it how you wanted it to be coded without tying your code to Session. Oh and one other benefit if done properly can be used to not tie your code to session in the web either.
I am using ASP.NET 2.0I am little bit confuse about using of Session Variable. I have a three page web application. When a user login, after verification of user credentials I get user ID from DB and store this ID in a session variable.Session("USERID") = 56by using this ID I can get 20 different values from database as User Full name, user date of birth, user location, user date of joining, User Commission rate etc. I need some of these values in Page 1, some in page 2 and some values needed in Page 301. After successfully login and getting the User ID, I take all these 20 values from Data Base and store these values in an ArrayList and store this ArrayList in a seesion and whenever I need to use any value I take these values from ArrayList which is save in Session variable.
