In my controller I'm error checking the query string and if the ID they specify doesn't exist I want to return a 404. While the path doesn't correspond with an item in sitecore I am trying to pull an item based on this ID.

We have a working nice 404 solution now. For some reason it doesn't pick up when I return HttpNotFound() to show the nice error message. But it does send the correct error code. I think it's reaching the IIS error page.

    <processor patch:after="processor[@type='Sitecore.Pipelines.HttpRequest.ItemResolver, Sitecore.Kernel']" type="CarnegieHall.Web.Pipelines.PageNotFoundResolver, CarnegieHall.Web" />
    <processor patch:after="processor[@type='Sitecore.Pipelines.HttpRequest.ExecuteRequest, Sitecore.Kernel']" type="CarnegieHall.Web.Pipelines.SetNotFoundStatusCode, CarnegieHall.Web" />
    <processor type="CarnegieHall.Web.Pipelines.SetNotFoundStatusCode, CarnegieHall.Web" />
      patch:after="processor[@type='Sitecore.Mvc.Pipelines.Response.GetPageItem.GetFromRouteUrl, Sitecore.Mvc']"
      type="CarnegieHall.Web.Pipelines.GetFromOldContext, CarnegieHall.Web" />

I think the issue is in the GetFromOldContext

public class GetFromOldContext : GetPageItemProcessor
    public override void Process(GetPageItemArgs args)
        Assert.ArgumentNotNull((object)args, "args");
        if (ItemNotFoundStatusRepository.HasFoundItemKey())
        args.Result = Context.Item;

In GetFromoldContext HttpContext.Current.Response.StatusCode is always 200.

  • Were you ever able to solve this issue ? return a HttpNotFoundResult in a controller and change the context.item to a custom 404 item ?

We recently stuck with this issue and add new pipeline processor for stating up the 404 status code forcefully.

Created a class -

public class Set404StatusCode : Pipelines.HttpRequest.HttpRequestBase
    public override void Execute(HttpRequestArgs args)
        var httpContext = args.HttpContext;

        if (HttpContext.Current.Response.StatusCode >= 500 || args.HttpContext.Request.RawUrl == "/")

        if (!args.HttpContext.Request.Url.LocalPath.EndsWith(Sitecore.Configuration.Settings.ItemNotFoundUrl, StringComparison.InvariantCultureIgnoreCase))

        Log.Warn($"Page Not Found on {Sitecore.Context.Site.Name}: {httpContext.Request.RawUrl}, current status: {HttpContext.Current.Response.StatusCode}", this);
        HttpContext.Current.Response.TrySkipIisCustomErrors = true;
        HttpContext.Current.Response.StatusCode = (int)HttpStatusCode.NotFound;
        HttpContext.Current.Response.StatusDescription = "Page not found";

And patch this to after Sitecore.Pipelines.HttpRequest.EndDiagnostics

<processor type="Project.Test.Pipelines.HttpRequest.Set404StatusCode, Project.Test" patch:after="*[@type='Sitecore.Pipelines.HttpRequest.EndDiagnostics, Sitecore.Kernel']">

Try this if it works for you.

  • this approach doesn't seems to work. The status code is changed into 404 but the custom error page is not rendered ...

  • @Centiyo - This code is only for setting up status ... for 404 page you need to make custom processor Commented Mar 11, 2022 at 6:14
