Hii,
I have been using session variables to maintain the session of a particular user accessing the application.
And on logout, i clear out all sessions and redirect it to login page.
But it doesn't work, since with the help of a browsers back button u can still perform all operations on the appication.
I would like to know the best possible solution for logout functionality.
A user after logout should not be able to access the app even through browsers back button.

Hi ,
Are you able to preform operation if you go to the page by browser back button even after logout.If yes,it shows that you have not check whether the session expires in each page.

Could you please elaborate on how can i check for session expiration.
I used to check for session.IsNewSession on each page.
But even that couldn't help,
hence would like to know how can i implement session expiration in every page.

Your login should be stored in the session. You don't need to write some code to expire the session in every page, just set the value you check to null, when someone logs out.

Check the session variable is not null in page load of each pages.If null redirect to login page.It will avoid you to perform operations.

if(Session["UserID"] != null)
{
}
else
{
Response.Redirect("Login.aspx");
}

This is only valid if a session for that variable was created and you are checking for its value.
But if someone requests this page directly, it will throw an error stating
Object refrence not set.

Buy a really basic book and read it. The code is CHECKING if the value is null.

Thanx for your suggestion and advice,
will surely do the same.
I have implemented my own logic on it.

What logic u applied.Beacuse back button take page from cache.so it take old session value.
so to avoid this wat u did?
I also want to know
|
|
|
|
|
U r right.
And to stop a user accessing a page even after logout, i simply disabled the browsers back button after logout through javascript.

U means u disable ur back button in ur whole project.

What was the Wrong with CG's Answer ?
|
|
|
|
|
No he wasn't wrong.
I had a bit concern, if a user tries to access the page directly, without following the normal routine, then the session variable which i would be checking on my page, would never have existed.
Hence i put out a check over there nd followed with the rest of the suggestions provided by all of u.

Make all the session variables null before logout.

You need source code for that to make changes.

Is that a COM dll? You don't need to register .NET DLL's.

i have the source code.
i'm using that component in my applicatiASP on.
here i register my component in component liberary.Before it's working fine .now i want to change the dll.
Shalln't need to register once again?

You seem to be pretty damn clueless. If you change a COM object, make sure you register the changed version. Simple really.

I've Edit the Dll source file and registered as well.But it doesn't reflect in the application.What would be the problem?
for Examble,
I have the connection string in my dll.I'd change the server and Database name.but it didn't reflect.Still remains in the same connection.
Thanks,
Mahesh
