RE: Katana and ASP.NET MVC together

OWIN can co-exist with MVC via the Asp.Net routing table, but there is no fail-over option.

http://katanaproject.codeplex.com/SourceControl/changeset/view/98f4571bdb80#src/Microsoft.Owin.Host.SystemWeb/RouteCollectionExtensions.cs

owin:HandleAllRequests is the opposite of co-existing.

Subject: Katana and ASP.NET MVC together

I am searching for a way to integrate OWIN via Katana into an existing ASP.NET MVC project.

I already played around with the configuration option "owin:HandleAllRequests", but had no success. When a request comes in I want it to be handled by the part of the application which uses owin first. If it cannot be handled by the OWIN part, it should be processed by ASP.NET MVC. Is there any way to do this with Katana?

Thanks in advance.

Would this be technically possible though? Could the OwinHttpHandler be modified to support fail-over? From my point of view this would make the integration with existing applications much easier. 

[Chris R]

Not to my knowledge, though if someone knows more about Asp.Net routing please pipe in here.  The more fundamental question is can you do route fail-over with any existing components?  The only means I've seen is via client or server side redirects (RedirectToRoute).  If there is no infrastructure for other HttpHandlers to do fail-over, then OwinHttpHandler can't do it either.

It would only be possible if your owin pipeline was (a) called from an HttpModule and (b) ran in its entirety before the event that the routing module hooks. But yeah, could be done, if the response is unaltered the rest of the request handling would occur as if nothing happened.

[Louis DeJardin]

Good news - I think we'll be getting this to work in Katana 1.1 - it
helps a lot if you want to write things like authn middleware.

that sounds promising

Is a fallback to ASP.NET MVC possible with the most recent version of Katana? If so, how would this work? Can the Stage Markers as described in http://www.asp.net/aspnet/overview/owin-and-katana/owin-middleware-in-the-iis-integrated-pipeline be used for that scenario? Which event does ASP.NET MVC use for it's routing?

[Chris R]

Fallback? You mean a fall-though?  Yes, if none of the middleware handle the request then it will automatically fall through to Asp.Net / IIS.  The stage markers should work fine in this scenario, except that you may need to use stages at MapHandler or earlier to ensure Asp.Net / IIS doesn’t take over the request too soon.
