I'm writing some logging code that is based on SessionID. However, when I log out (calling Session.Abandon), and log in once again, SessionID is still the same. Basically every browser on my PC has it's own session id "attached", and it won't change for some reason. My Session config looks like this:
<sessionState
mode="InProc"
timeout="1" />
To avoid session fixation/hijacking we are heeding the common advice to create a new ASP.Net session for a user after authentication. Sounds simple enough. When a user authenticates we call Session.Abandon() the session ID cookie Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", "") then redirect the user.
However, how do we know on the new page that the user has logged in? We cannot check a session variable because there are none, we just started a brand new session.
I would swear, though I cannot find it now, that on this site someone explained how you can abandon a session and then get the next subsequent session ID. This way you could store that information. Then on the "Start Page" a new session would begin and that page could look up the old Session based on the new ID and validate that a user logged in.
So, are there any masters of the ASP.Net Session classes that know how to do this?
How to get rid of Session.sessionID when abandoning the session?
Scenario : I abandon a session and create a new session again. This time the sessionID generated remains the same as earlier.
In ASP.NET should we call Session.Abandon() when an unhandled exception occurs?There are many end users that hit "refresh" or "back" in the web browser in order to resubmit the request.I would like to prevent this behavior by resetting the context.TIA.
View 2 RepliesWhat is the difference between Session.Abandon() and Session.Clear() in ASP.Net?
View 1 Replieson click of logout button, i want to call a web service method that will get that particular user's session and call its abandon method. But how can i pass that session variable to that web method ?
Calling of web method is done through java script.
Session.Abandon() in not working ASP.NET 2.0 (C#) in a few cases. In the same application its working fine in other places.
< sessionState
mode="StateServer"
cookieless="false"
timeout="20" />
The session mode is "SateServer".
I have just added the following to the very last page of my application.
[Code]....
And then i have this on each of the pages before the last, within my Page_load:
[Code]....
I have different sessions thruout the application process, but this one session is only set at the beginning of the process and once i kill it on the last page, any attempt to hit Back or trying to access any page directly without first starting, i need to force them to the beginning, what am i missing or doing wrong?
sessID is set on page 1 and is available until you get to the last page. Where i added the Session.Abandon(); Now if i get to the last page and hit back before the refresh occurs, im able to go back, but the page comes up with null reference for other sessions that are obvisously cleared / killed with the abandon. So i should have to check for each session should i? I mean if the abandon killed them all, then checking for the main session should be enough right?
In my ASP.NET application I need to allow only one session for a user ? When a user does login more than once, I want to get to user's previous session and abandon it. I'm keeping track of all user sessions by means of session id. But Session.Abandon is available only for the current session associated with a request and not previous sessions. I have the session id of the user's previous session but how can I end it ?
View 3 Repliesi allow my admin to login from his login page and login information verified and stored into an session after that, he visited into an client page, there is an logout button this will visible whether session has the user id or admin user id else it'll be invisible.
now the scenario is:
1. admin logged into admin page
2. then in the address bar type the client page name
3. now the client page is check whether has the userid or admin user id in Session, now the session has admin user id so, its show the Logout button.
4. from this client page, the admin clicks on Logout button, here i have Abandon the session and moved into the admin login page.5. now again admin types the same client page name in the address bar from his login page(but now he didnt logged in).6. this time i set the break point on client page_load event but its not hitting the event also its visible the Logout button also.so, how its not hitting the page_load event and why the logout button is visible after loggedout.
How do I abandon the session when the user closes the browser window instead of pressing the logout button in ASP.Net 3.5 application.
View 5 RepliesWhy does the property SessionID on the Session-object in an ASP.NET-page change between requests?
I have a page like this:
...
<div>
SessionID: <%= SessionID %>
</div>
...
And the output keeps changing every time I hit F5, independent of browser.
I've seen this work correctly in other projects.
I'm storing the session IDs of the logged-in users in a database, so I need to kill some sessions using the session Ids stored in the database, but unfortuently I'm not able to get any session using the seesion ID so that I can kill it.
View 1 RepliesI'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 RepliesI am searching to find a way to read and write on session data but with out having the HttpContext.Current.Why I won to do that ?, because I wish to make some action with the user Session after the page have been close and unloaded. For example, a user load and see a page, then I create a thread to make some action and let user go. Inside this thread I like to read the session data, but in this case HttpContext.Current is not exist any more.
So is there a way to read Session Data knowing just the session id.I store my session inside an sql server, and I see them... its there on table ASPStateTempSessions . How can I read them "offline" and manipulate them ?
I hav a problem where I wanted to share session state between main page and subdomain page (example between [URL]. Naturally, in this case, the webserver will give me a different session id because the session id is bound to the domain.
But how can i override the sessionid of my main page when I come back to it?
i want to generate the new sessionid in the same httpcontext once the user is successfully authenticated.so, how can i do that ? ( please dont ask why do you want it, i got such kind of requirement).
View 3 RepliesI want to be able to log when a user ends their session on our application and record whether it was a sign out or a the session expired. I am using
cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));
to set a new sessionId on sign out, but when the session expires, the sessionId is reused if the browser instance is not closed. In my web.config I have used
<sessionState mode="InProc" timeout="1" cookieName="session" regenerateExpiredSessionId="true" />
but still get sessions reused. I can't kill the cookie in Session_end() because I don't have access because there is no HttpContext or request, so I can't reset it that way. how I can force a new sessionId from the Global.asax.cs file?
Membership/Role/Profile providers API appeared in early days of asp.net Nearly everytime I can't live with standard API & have to add some extra functionality (for sorting, retrieving e.t.c.). I also have to use different database structure often (with foreign key to some tables for example) or think about performance improvements.
These considerations forced teams I took part in to build own providers but I can't stand to implement providers API (because we don't use 70% of standard functionality at least). Moreover, providers that were built for exact projects were rarely reused.
I wonder if someone found swiss-knife early-days-API providers implementation that is usefull for any kind of project without refactoring. Or do you use your own implementations of early-days-API's Or may be you abandon standard architecture and use lightweight implementations?
I need to save a value to a session variable from a javascript function, and then be able to call this value back from the Session into another javascript function during post back.

In my ASP.net 3.5 application I'm calling an asmx webservice that is part of the application. Calling the webservice entends the user's session timeout, which is undesirable in this case.How can I call a webservice on my server without extending the session timeout? Is there a way in IIS to designate it as being outside of the session scope? (apologies if I'm using incorrect terminology) Can I designate a directory in the ASP.net web.config file as being outside the session?
