The browser can affect session state information. In order to maintain session information in the 'internet' zone, either "First Party Cookies" and/or "Always
allow session cookies" must be allowed in the Internet Explorer.
< In IE: Menu: Tools -> Internet Options for the Internet Options panel. Tab: Privacy, button: Advanced for the "Advanced Privacy Options dialog. >
These settings do not apply to the 'local intranet zone' where session information is maintained despite the options chosen here. This leads to the
IWOMDS ('It Works On My Desk Syndrome')
Other reasons for the loss of session information are:
* Session timeout. In ASP, this is an IIS setting. In ASPX, this is set in the web.config file for the application.
* If the IIS worker process fails for some reason, such as an application crash, a change or anti-virus touch of the global.asp file, the session information is
reset.

This is what I think, not necessarily what is accurate!

| I am using Session variables in my ASP application. I have tested the
| application on a Win2k professional and it works fine. When the same web
| app is installed on a win2k advanced server from the client browser when the
| app is accessed the session variable returns null inspite of a value being
| already set. I have checked the IIS enable session state settings. When i
| use the server machine as client and access the app as localhost then the
| session variable has correct value.
|
| How can this be solved? What other settings if any, need to be changed to
| get it work.
|
| Thanks,
