Hi Ben,
   I am not sure how it is Done Code Project, but a simple logic whihc i can
derive is have the LinkButton on the webpage for downloading, when the user
clicks on the download link. in the LinkButton_Click event Check for the
Valid User something like
if(Session["UserName"].ToString().Length<=0)
    Server.Transfer("Login.aspx");
else
    Response.write("<Script>location.href='Download.zip'</script>");

Hope this works for you i do remember doing this a long time back.. i do not
have the code right now.

 but this will have impact on the post back!!

so the Redirecting
