How To Retrive A Value Using A Query String?

Hello,

I would like to keep some values as session variables while the user is loged in, but i am missing some part of how to implement it.

This is what I have:
<script runat="server">

Protected Sub Login1_Authenticate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.AuthenticateEventArgs)

Dim conn As SqlConnection
Dim cmd As SqlCommand
Dim cmdString As String = "SELECT users.username, users.password, users.FirstName, users.LastName, users.CompanyId, Company.CompanyName, users.SecurityLvl FROM users LEFT OUTER JOIN Company ON users.CompanyId = Company.CompanyId WHERE (users.password = @Password) AND (users.username = @Username)"

conn = New SqlConnection("Data Source=GDB03SQL;Initial Catalog=GDBRemitance;Persist Security Info=True;User ID=remitance;Password=remitance")
cmd = New SqlCommand(cmdString, conn)
cmd.Parameters.Add("@Username", SqlDbType.VarChar, 50)
cmd.Parameters("@Username").Value = Me.Login1.UserName
cmd.Parameters.Add("@Password", SqlDbType.VarChar, 50)
cmd.Parameters("@Password").Value = Me.Login1.Password


conn.Open()
Dim myReader As SqlDataReader
myReader = cmd.ExecuteReader(CommandBehavior.CloseConnection)
If myReader.Read() Then

FormsAuthentication.RedirectFromLoginPage(Me.Login1.UserName, False)
Else
'Response.Write("Invalid credentials")
End If
myReader.Close()

End Sub
</script> I would like to know how can I get now the "user.FirstName" and pass it to a session variable???
how should I code it?

thanks,
