Example of Umbraco 6.1's IContentFinder

MyApplication.cs

using Umbraco.Core;
using Umbraco.Core.Services;
using Umbraco.Web.Mvc;
using Umbraco.Web.Routing;

namespace Our.Umbraco
{
	public class MyApplication : ApplicationEventHandler
	{
		protected override void ApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
		{
			ContentFinderResolver.Current.InsertTypeBefore<ContentFinderByNotFoundHandlers, ContentFinderForWhatever>();
			base.ApplicationStarting(umbracoApplication, applicationContext);
		}
	}

	// the example here is to have a 'virtual url'.
	// this is required on a specific DocType, after @level=3
	public class ContentFinderForWhatever : IContentFinder
	{
		public bool TryFindContent(PublishedContentRequest contentRequest)
		{
			if (contentRequest != null)
			{
				var path = contentRequest.Uri.GetAbsolutePathDecoded();
				var parts = path.Split(new[] { '/' }, System.StringSplitOptions.RemoveEmptyEntries);
				if (parts.Length > 2)
				{
					var level3 = string.Concat('/', string.Join("/", parts.Take(3)), '/');
					var node = contentRequest.RoutingContext.UmbracoContext.ContentCache.GetByRoute(level3);

					if (node.DocumentTypeAlias == "Whatever")
						contentRequest.PublishedContent = node;
				}
			}

			return contentRequest.PublishedContent != null;
		}
	}
}

For reference, original code was used from a forum post on Our Umbraco:

Hey Lee,
Not sure what the purpose of this is and what it's attempting to do.

It solved a specific problem that I had :-)

The example here is to create 'virtual URLs'. Say on a specific DocType, (called "Whatever", @Level = 3), you wanted to have deeper URLs for the same content.

e.g.

• /gb/en/maps - this is an actual node
• /gb/en/maps/europe - this is a virtual URL, that needs to use the parent 'maps' node.
• /gb/en/maps/europe/uk - another virtual URL, that needs to use the 'maps' node (at @Level = 3)
  ... and so forth

Now I don't need to create fake/stub content nodes for all the URLs/pages.

Ah ok interesting use case. Will be starring this...

This is great and just what I need. A good example I need it for is the blog aspect of a website.

In one area I have a central repository for blogs/posts so it's easy to manage

website.com/blog/black-labradors-are-great-pets

But to improve SEO we might have a landing page for dogs and be able to access the posts under a virtual url as suggested above.

website.com/dogs/black-labradors-are-great-pets

Hi Lee,

Does the url influence the rendering of the page at all ? (I guess a hijack controller could look at the url and parse it again ?)

If data from the url needs to be used would it be best to follow [http://shazwazza.com/post/custom-mvc-routes-within-the-umbraco-pipeline/](Shannons post on custom MVC routes within the Umbraco pipeline) ?

Thanks,
Hendy

Hi Lee, I stumbled across this when trying to address a similar problem however I did hit the occassional null value on the node so amended the following:

if (node.DocumentTypeAlias == "Whatever")
to
if (node != null && node.DocumentTypeAlias == "Whatever")
Thanks, Simon
