How do I intercept all routes that have a base controller parent path in them in Umbraco 7

I have looked all around at Umbraco route hijacking and using IContentFinder and IUrlProvider and I am still a little lost on how to do what I want.

I have a controller that matches a document type which I have a base page for in Umbraco.

I made a document type called "Ads" and a controller called "AdsController: RenderMvcController"

I have a basic method to catch all like this

public ActionResult Index(RenderModel model)

It works if the route is like this

http://www.example.com/Ads?parent=Cars&child=American

but I want it to hit if I do this :

http://www.example.com/Ads/Cars/American

So basically nice MVC routing. I think content provider only lets you find content that is in your actual tree and this content isn't. I am going to find it using C# in the DB and render a custom view and return it using a custom view model.

I know how to do the view part. Just need to know how to hijack all routes under a parent route so my base controller method hits without having to create a bunch of templates or action methods for each AD category type.

Hi Kyle

I did something similar to this using a content finder - adapting for your case I think it'll be something like this:

        public bool TryFindContent(PublishedContentRequest request)
        {
            // We are looking for URLs of the form (/[ads landing page]/[parent category]/[child category]/
            var urlParts = request.Uri.GetAbsolutePathDecoded().Split(new[] { '/' }, StringSplitOptions.RemoveEmptyEntries);
            if (urlParts.Length == 3)
            {
                // Check to see if request is below the ad landing page, if so do silent redirect to it passing the categories
                var landingPageUrl = "/" + string.Join("/", urlParts[0]);
                var firstLevelContent = request.RoutingContext.UmbracoContext.ContentCache.GetByRoute(landingPageUrl);
                if (IsAdPage(firstLevelContent))
                {
                    // Store the store Id in the HTTP context
                    HttpContext.Current.Items["parent"] = urlParts[1];
                    HttpContext.Current.Items["child"] = urlParts[2];

                    // Set the content to be the ads landing page - which will take us to our hijacked
                    // route controller to render the detail page
                    request.PublishedContent = firstLevelContent;

                    // Return true to indicate content found
                    return true;
                }
            }

            return false;
        }

        private bool IsAdPage(IPublishedContent content)
        {
            return content != null && content.DocumentTypeAlias == "Ads";
        }

Then in your controller you can check for the existing of those items in ControllerContext.HttpContext.Items["parent"] and ControllerContext.HttpContext.Items["child"] and do what you need to do with pulling the information from the external database.
