Need help Redirect From Login Page

Hi,

I am using Classic Asp and VBscript.

I use session time out to check if the user is authenticated.
If Session("Authenticated") = 0 Then
Response.Redirect ("Login.asp")

The Login Page redirect the user to Mypage1.asp
Session("Authenticated") = 1
Session.Timeout = 10
Response.Redirect ("Mypage1.asp")


Now when i am in Mypage2.asp and the session time out occurs i get redirected to the login page.

My problem is

When i LOGIN (after Session Timeout) i need to redirected to where i was , say Mypage2.asp?num1=10?month=october

Can somebody help me with this please.
