title: Is there a way to convert OwinRequest to HttpRequestBase?
body: <p>I'm writing a piece of Owin Middleware, where I need to use some legacy code, which uses HttpRequestBase as method argument. The legacy code does not follow SOLID so It's impossible to extend it to use OwinRequest instead of HttpRequestBase</p>
  
  <p>Is there an extension (or a way) to convert an OwinRequest into a HttpRequestBase?</p>
