// A request context provides request handling for a set of related browser
// or URL request objects. A request context can be specified when creating a
// new browser via the CefBrowserHost static factory methods or when creating a
// new URL request via the CefURLRequest static factory methods. Browser objects
// with different request contexts will never be hosted in the same render
// process. Browser objects with the same request context may or may not be
// hosted in the same render process depending on the process model. Browser
// objects created indirectly via the JavaScript window.open function or
// targeted links will share the same render process and the same request
// context as the source browser. When running in single-process mode there is
// only a single render process (the main process) and so all browsers created
// in single-process mode will share the same request context. This will be the
// first request context passed into a CefBrowserHost static factory method and
// all other request context objects will be ignored.
