Hi all, so this is the scenario:

I have a base class for all login-controlled pages:

public class SessionControlledPage : Page
{
    protected virtual void Page_Load(Object sender, EventArgs e)
    {
        Response.AddHeader("Refresh", Convert.ToString(Session.Timeout * 60 + 5));
        if (Session.IsNewSession)
        {
            Response.Redirect("~/login.aspx");
        }
    }
}

And a regularpage.aspx page that inherints from the base class:

public partial class RegularPage : SessionControlledPage
{
    override protected void Page_Load(Object sender, EventArgs e)
    {
        base.Page_Load(sender, e);

        Server.Transfer("~/otherpage.aspx");
    }
}

Now let's say the original URL was http://localhost/regularpage.aspx and that Session.Timeout = 5. The problem appears when the refresh happens after the transfer takes place. I'm getting a 404 Not Found error and the URL changes for http://localhost/305. Notice that 5 * 60 + 5 = 305.

Do you know why is this happening? got a solution?

PD: I use transfer because I need to access some properties of regularpage.aspx on otherpage.aspx, maybe you could provide another solution for this too.
