ASP Session

Sessions in ASP are used to store user-specific information on the server, enabling persistent state management across multiple pages. Each user gets a unique session, which can store variables and data for the duration of their visit.

Key Topics

Storing Session Data

Example

<%
    Session("username") = "JohnDoe"
    Response.Write("Session data has been stored.")
%>

Explanation: This example stores a user-specific value, JohnDoe, in the session variable username.

Retrieving Session Data

Example

<%
    If Not IsEmpty(Session("username")) Then
        Response.Write("Welcome, " & Session("username") & "!")
    Else
        Response.Write("No session data found.")
    End If
%>

Explanation: This example retrieves and displays the value of the session variable username, if it exists.

Clearing Session

Example

<%
    Session.Abandon()
    Response.Write("Session has been cleared.")
%>

Explanation: This example clears all session data for the current user by calling the Session.Abandon method.
