Custom Application Page for ListID issue

Scenario:
You want to provide a link to a particular System Application Page, but all the application pages accepts parameter in form of some ID which is not unique in different environments.

Solution:

Redirect.aspx(12\Template\Layouts\Client\):

<%@ Assembly Name="Microsoft.SharePoint, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

<%@ Page Language="C#" MasterPageFile="~/_layouts/application.master" Inherits="Microsoft.SharePoint.WebControls.LayoutsPageBase" %>

<%@ Import Namespace="Microsoft.SharePoint" %>

<script runat="server">
    protected override void OnLoad(EventArgs e)
    {
        SPWeb site = this.Web;
        
        Guid listID = default(System.Guid);

        string listName = Request.QueryString["List"];
        string pageName = Request.QueryString["Page"];

        if (listName != null && pageName != null)
        {
            foreach (SPList list in site.Lists)
            {
                if (list.Title.ToLower() == listName.ToLower())
                {
                    listID = list.ID;
                    break;
                }
            }

            Response.Redirect(this.Web.Url + @"/_layouts/" + pageName + ".aspx?List=" + listID);
        }
    }
</script>

<asp:Content ID="Main" ContentPlaceHolderID="PlaceHolderMain" runat="server">
Redirection Page - Please pass the proper Request Query Parameters to get the redirection to work.</asp:Content>

<asp:Content ID="PageTitle" ContentPlaceHolderID="PlaceHolderPageTitle" runat="server">Redirection Page</asp:Content>

<asp:Content ID="PageTitleInTitleArea" runat="server" ContentPlaceHolderID="PlaceHolderPageTitleInTitleArea">Redirection Page</asp:Content>

Usage:
Now you can call this Redirect page as

http://localhost/_layouts/client/redirect.aspx?List=Tasks&Page=listedit

and you will be redirected to the List Settings ( listedit.aspx ) of the Tasks list.
