We need to have a separate NuGet package for Mono to support Unix Sockets. FastCgiNet should do the same before we can do this.
Self-Explanatory.
IIS has two options for FastCGI - named pipes and TCP. FOS supports unix named pipes and TCP. However, the way that IIS uses TCP is not compatible with the way that FOS uses TCP.
In the case of named pipes, IIS creates a named pipe and passes it to the FastCGI process as StdIn. The FastCGI process is then expected to duplicate the handle and use the pipe for reading/writing.
In the case of TCP, IIS opens a transient port and then passes a handle to the FastCGI process also as StdIn. The FastCGI process is then expected to duplicate the handle and use it for read/writing. IIS will not connect to a FastCGI process listening on a specific port.
A possible fix would be to add a BindToIisStdIn method to SocketListener that would pull the correct handle/socket from StdIn in order to communicate with IIS.
I got FOS from nuget and tried to use it with Microsoft.AspNet.WebApi.Owin, and got the following exception when making a request:
System.ArgumentException: Cannot bind to the target method because its signature or security transparency is not compatible with that of the delegate type.
at System.Delegate.CreateDelegate(Type type, Object target, String method, Boolean ignoreCase, Boolean throwOnBindFailure)
at Fos.Owin.OwinMiddleware.BuildHandler()
at Fos.Owin.OwinMiddleware.get_Handler()
at Fos.Owin.OwinMiddleware.Invoke(IDictionary`2 owinParameters)
at Fos.Listener.FosRequest.ProcessRequest()
I cloned the repository and debugged through it. The problem appears to be that FosAppBuilder expects all middleware to have an Invoke method can be created as a delegate of type Func<IDictionary<string, object>, Task>. Several of the newer middlewares have an invoke method signature of Func<Microsoft.Owin.IOwinContext, Task>. The System.Web.Http.Owin,HttpMessageHandlerAdapter middleware registered by UseWebApi() is one of these middlewares.
Microsoft.Owin.Builder.AppBuilder already handles conversion between these two signatures and by having FosAppBuilder inherit from Microsoft.Owin.Builder.AppBuilder, I was able to successfully use the WebApi middleware over fastcgi for my application.
Wired up a test application with UseActiveDirectoryFederationServicesBearerAuthentication, and get the following exception:
System.NotSupportedException: The OWIN key 'server.OnSendingHeaders' is not available for this request.

The FosRequest class would need to be able to handle the common key server.OnSendingHeaders (defined here: http://owin.org/spec/spec/CommonKeys.html#_6._Common_keys) in order to use these middlewares.
