I have a asp.net project with c# code behind. I have a static class called GlobalVariable where I store some information, like the currently selected product for example.
However, I saw that when there are two users using the website, if one changes the selected product, if changes it for everybody. The static variables seem to be commun to everybody.
I would want to create (from the c# code) some kind of session variable used only from the c# code, but not only from the page, but from any class.

The Session object stores information about, or change settings for a user session. Variables are stored in a Session object hold information about one single user. And are available to all pages in one application. Common information stored in session variables are name, id, and preferences.
Sessions values can be stored for the duration of the visitor's session on your site. Most cases, they are stored in server memory. You can configure session to store either in State server or in SQL Server. In ASP.NET MVC, you can create and access session variables using HttpContext.
Yes static variables are shared by the whole application, they are in no way private to the user/session.
To access the Session object from a non-page class, you should use HttpContext.Current.Session.
