ASPX page loading data from last session

I'm creating a C# application with a ASP.net frontend, however I'm having a problem at the moment. I want to the user to enter some information, which once submitted, will be displayed within a listbox on the page which works fine. However, once I close the page, stop debugging the program and run it again - the information is still displayed but I want it to start off blank. Here if the ASPX page that I think if causing the issue, it's driving me mad.

public partial class CarBootSaleForm : System.Web.UI.Page, ISaleManagerUI
{
    private SaleList saleList; 

    protected void Page_Load(object sender, EventArgs e)
    {

        if (IsPostBack && Application["SaleList"] != null)
        {
            LoadData();
        }
        else
        {
            saleList = (SaleList)Application["SaleList"];
        }

        if (saleList != null)
        {
            UpdateListbox();
        }

    }

    private void UpdateListbox()
    {
        lstSales.Items.Clear();

        if (saleList != null)
        {
            for (int i = 0; i < saleList.Count(); i++)
            {
                lstSales.Items.Add(new ListItem(saleList.getSale(i).ToString()));
            }
        }
    }

    protected void btnAdd_Click(object sender, EventArgs e)
    {
        Application.Lock();
        Application["SaleList"] = saleList;
        Application.UnLock();

        Response.Redirect("AddSaleForm.aspx");
    }

}

Forget the LoadData() within the page load as it's not actually loading anything at the moment :)

Any help is really appreciated!

The variables stored in Application state are not flushed unless you restart the web server, so you will need to use the iisreset commmand (on command-line) if you are using IIS, or you will need to stop the ASP.NET web server (use the tray icons) after each debugging session.

if it is not postback you can add Session.Abandon(); in the else block in Page_load.
