To keep session data, you will have to keep a copy of the open sessions
during restart.<br>
<br>
I have not tried to do this, but you might be able to make a file copy
of the "Session" folder and files before the restart,<br>
and copy it back in after.<br>
<br>
If the server stops responding, you will not be able to query it for
open sessions, so I think the above approach is pretty much the only
way.<br>
