If you read these blog post:
SharePoint 2010 ‘Page not found (404)’ page the way it should be and this Inconvenient Catalog Item Page and ‘Page not found’ (404) experience from the master Waldek Mastykarz , and you're here, you're one step closer to the solution.
This blog post extends the Mastykartz strategy with just few lines of code.
Let's assume you developed those components:
MaventionCatalogItemReuseWebPart simply redirects to site collection page not found url, but, since this is a server side redirection, the HTTP status code is 302 and the redirect location it's also well known, so i just modified PageNotFoundHttpModule in this way.

This blog post extends the Mastykartz strategy with just few lines of code.
Let's assume you developed those components:
- PageNotFoundHttpModule from SharePoint 2010 ‘Page not found (404)’ page the way it should be
- PageNotFoundWebPart from SharePoint 2010 ‘Page not found (404)’ page the way it should be
- Something like MaventionCatalogItemReuseWebPart from Inconvenient Catalog Item Page and ‘Page not found’ (404) experience
MaventionCatalogItemReuseWebPart simply redirects to site collection page not found url, but, since this is a server side redirection, the HTTP status code is 302 and the redirect location it's also well known, so i just modified PageNotFoundHttpModule in this way.
public class PageNotFoundHttpModule : IHttpModule
{
#region Const
const string URL_RELATIVE_PAGENOTFOUND = "/Pages/PageNotFoundError.aspx";
#endregion
#region Fields
private HttpApplication webApplication;
#endregion
#region Public methods
public void Init(HttpApplication context)
{
webApplication = context;
webApplication.PreSendRequestContent += new EventHandler(webApplication_PreSendRequestContent);
}
public void Dispose()
{
}
#endregion
#region Event handlers
void webApplication_PreSendRequestContent(object sender, EventArgs e)
{
HttpResponse response = webApplication.Response;
HttpRequest request = webApplication.Request;
if ((response.StatusCode == 404 && string.Compare(request.Url.AbsolutePath, URL_RELATIVE_PAGENOTFOUND, StringComparison.InvariantCultureIgnoreCase) != 0) ||
(response.StatusCode == 302 && string.Compare(response.RedirectLocation, URL_RELATIVE_PAGENOTFOUND, StringComparison.InvariantCultureIgnoreCase) == 0))
{
webApplication.Server.TransferRequest(URL_RELATIVE_PAGENOTFOUND);
}
}
#endregion
So what i added is essentially a new or condition.
