Using a Re-direct following an Upgrade

It is generally considered better practice to send an HTTP code of 301 (rather than 302 - temporary redirect) to indicate a permanent redirect so that search engines and the like will update their index to reflect the new URL for the resource (provided by a Location header).

The following page snippet achieves this and preserves the query string. This should be in a page with the same name as your main iShare page.

<%@ Page Language="C#" %>
<script runat="server">
  protected override void OnLoad(EventArgs e)
  {
  
      string location = "http://maps.mendip.gov.uk/";
      location += (Request.QueryString.Count > 0) ? "?" + Request.QueryString : "";
 
      Response.Status = "301 Moved Permanently";
      Response.AddHeader("Location", location); 
      
      base.OnLoad(e);
  }
</script>
