When the headerViewModel is being build I want to detect if the startpage is loading. Any pointers on how to do that?

Litium version: 7

I don’t know if it’s the correct Litium way to do this, but an easy way would be to resolve the HttpContext in the controller.

You can try to use `_requestModelAccessor.RequestModel.CurrentPageModel.Page.ParentPageSystemId == Guid.Empty` in the `Litium.Accelerator.Builders.Framework.HeaderViewModelBuilder.Build`-method.

I had that exakt line earlier and it didn’t work when I tried to navigate to a category page. The `ParentPageSystemId` was still an empty Guid. In the `build-method` you refer I changed to look at the `RawUrl` of the request and compare it to the startpageUrl. Got it working for now

For all product catalog pages the start page will be the “active” page.

To not compare the url you can also inject the `Litium.Web.Routing.RouteRequestInfoAccessor` and make the check like this

```auto
            var onStartPage = _requestModelAccessor.RequestModel.CurrentPageModel.Page.ParentPageSystemId == Guid.Empty
                && !(_routeRequestInfoAccessor.RouteRequestInfo.Data is Litium.Web.Products.Routing.ProductPageData);

```
