This is part of a set of articles that are my developer notes for working with Nancy. Taken from the Nancy introduction, "Nancy is a lightweight, low-ceremony, framework for building HTTP based services on .Net and Mono." It's (she's?) great for building microservices and other things.
Other directories can be included by adding to NancyConventions.StaticContentConventions property. Do this by overriding the ConfigureConventions method in your bootstrapper.
The shot from Fiddler below shows a before and after. The calls from 5-8 were made before the additions to the bootstrapper. The later calls show that the changes enabled Nancy hosting the files in those directories.
