Deleting Session Variables after use

[Simon Harvey]

Hi all,

Is it prudent to delete items that you've stored in the session if you are
sure that these values won't be needed again?

I'm also wondering if things would be arsed up if the user went to a page
that deleted session information and then used his/her back button to go to
a precious page. Presumably the session data would be gone and my app would
get mighty pissed

Is that the case

Any help would be very greatfully received.

Many thanks

Simon

It's a good practice to delete the session variables once you know that its
no more required, this will help you to free your server memory and hence
making your app more efficient.

You can look in the application level error handling, which will redirect
the user to some friendly error page. Also you can check for the session_end
event in the global.asax .
