      <Comment>OWIN support for Sitecore.

Adds an extension point to use OWIN middlewares through the Sitecore pipeline.

How to use?

1. Add reference to the Sitecore.Owin.dll
2. Implement a class with a public method "void Process(InitializeOwinMiddlewareArgs args)"

public class SampleOwinMiddleware
{
 public void Process(InitializeOwinMiddlewareArgs args)
 {
   args.App.Use((context, next) =&gt;
   {
     context.Response.Headers.Append("Yes", "it works");
     return next();
   });
 }
}

3. Patch the sitecore/pipelines/initializeOwinMiddleware pipeline to add your processor</Comment>

      <Readme>Before installing:

1. If you don't have already configured OWIN in your Sitecore instance, than you need to add a new setting into the web.config configuration/appSettings (otherwise, it will conflict with SolrNet.Startup class from the SolrNet.dll):

&lt;appSettings&gt;
   ...    
   &lt;add key="owin:appStartup" value="Sitecore.Owin.Startup, Sitecore.Owin" /&gt;
&lt;appSettings&gt;

2. If you already have OWIN's Startup class, then you should:

Inherit Sitecore.Owin.Startup class by your implementation.
Add the override keyword to your Configuration method and call it's base implementation anywhere inside:

public override void Configuration(IAppBuilder app)
{
  base.Configuration(app);
  ...
