A contrived but fun example of how to build a OWIN compliant file server using Symbiote.

OWINFileServer.cs

using System;
using System.Collections.Generic;
using Symbiote.Core;
using Symbiote.Http;
using Symbiote.Http.Impl;
using Symbiote.Http.Owin;
using Symbiote.StructureMap;
using Symbiote.Daemon;
using Symbiote.Messaging;
using Symbiote.Actor;

namespace FileServerDemo
{
    public class Program
    {
        static void Main(string[] args)
        {
            Assimilate
                .Core<StructureMapAdapter>()
                .Daemon(x => x.Arguments(args))
                .Actors()
                .Messaging()
                .HttpHost(x => x
                    .ConfigureHttpListener(l => l.AddPort(8989))
                    .RegisterApplications(a => a.DefineApplication<FileServer>(r => r.Url.StartsWith("/file")))
                    )
                .RunDaemon();
        }
    }

    public class FileServer : IApplication
    {
        public void Process(IDictionary<string, object> requestItems, Action<string, IDictionary<string, IList<string>>, IEnumerable<object>> respond, Action<Exception> onException)
        {
            var request = requestItems.ExtractRequest();
            respond
                .Build()
                .AppendFileContentToBody( request.Url )
                .Submit( HttpStatus.Ok );
        }
    }

    public class HostService : IDaemon
    {
        public IHost Host { get; set; }

        public void Start()
        {
            Host.Start();
        }

        public void Stop()
        {
            Host.Stop();
        }

        public HostService(IHost host)
        {
            Host = host;
        }
    }
}
