Well Known PipelineContributors

By default, OpenRasta executes a number of “well-known” pipeline contributors for every request. When you’re writing your own contributors, you need to be aware of this execution order so you can place your contributor at the most appropriate point in the pipeline. Here’s a list of the well known contributor types names – shown here in one possible order of execution – that you might need for a call to IPipelineRunner.Notify(Method).Before<TContributor>() or IPipelineRunner.Notify(Method).After<TContributor>(), and the default implementation.
