Can we be sure here that there is an adapter for request to a
IWebBrowserOriginatingRequest?

I'm pretty sure that you can rewrite:
  queryAdapter(web_service_request, IWebBrowserOriginatingRequest)
as
  IWebBrowserOriginatingRequest(web_service_request, None)

Not sure if you think this is better or not.
