Inbound request pipeline

    The inbound process is triggered by the Umbraco (http) Module. The published content request preparation process kicks in and creates a PublishedContentRequest.

    The PublishedContentRequest object represents the request which Umbraco must handle. It contains everything that will be needed to render it. All this happens when the Umbraco modules thinks it's a document to render.

    public class PublishedContentRequest
      public Uri Uri { get; }

    There are 4 important properties, which contains all the information to find back a node:

    public bool HasDomain { get; }
    public Domain Domain { get; }
    public Uri DomainUri { get; }
    public CultureInfo Culture { get; }

    Domain contains: "", while Uri is "".

    It contains also the content to render:

    public bool HasPublishedContent { get; }
    public IPublishedContent PublishedContent { get; set; }
    public bool IsInitialPublishedContent { get; }
    public IPublishedContent InitialPublishedContent { get; }
    public void SetIsInitialPublishedContent();
    public void SetInternalRedirectPublishedContent(IPublishedContent content);
    public bool IsInternalRedirectPublishedContent { get; }

    Contains template information and the corresponding rendering engine:

    public bool HasTemplate { get; }
    public string TemplateAlias { get; }
    public RenderingEngine RenderingEngine { get; }
    public bool TrySetTemplate(string alias);
    public void SetTemplate(ITemplate template);

    You can subscribe to the event to know when the PublishedContentRequest is ready to be processed. It's up to you to change anything (content, template, ...):

    // public static event EventHandler<EventArgs> Prepared;
    PublishedContentRequest.Prepared += (sender, args) =>
      var request = sender as PublishedContentRequest;
      // do something…
