How to exit from iframe? I have a pages called `Master.aspx`, `Parent.aspx` (inside that iframe is there), `Child.aspx`. I am calling `Child.aspx` inside `Parent.aspx` page using an iframe.

If `strBillingAddress1` is null then I need to redirect to page `Master.aspx`. It is redirecting but showing inside iframe. I don't want this behavior. I need to open as new page itself?

This is the code:

```
If String.IsNullOrEmpty(Session("strBillingAddress1")) Then
    Response.Redirect("Master.aspx")
    Response.End()
End If

```

Plz help me..
Thanks
