dotnet academic: I have a VB.NET web application running on the departmental server. This application saves data from the controls on the form to a session variable when the user clicks the submit button. If the user leaves the page and then returns to the page, the page-load event retrieves the session variable data and puts it back in the control boxes on the form

The program works fine from my office

When I open InternetExplorer in the lab and access the page, the program does not restore the data from the session variables

Does anyone have any clues

Session variable depends on cookies..
If your browser setting made cookie disabled, you can't access session value..
