With gb.web.form, the session is automatically created for each user that connect to the application. It automatically remembers the variables associated with the webforms. It is up to you to implement a login/password check to identify the user, and modify your application according to its rights.

With a web application, the only way to keep things persistent is using the Session object. With a WebForm, you can store permanent things by using it like an array, which use internally the Session object of course. So you can write: Export Public Sub WebButton1_Click() Me["my_A"] = "sharon" End Public Sub WebButton2_Click() WebButton2.Text = Me["my_A"] End So, never forget that your application is a web application that is not persistent between two events (the request is mostly the full handling of one event coming from the web browser. The response is the refresh of the web browser contents).
