// 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 cef_browser_host_t static factory functions or when creating
// a new URL request via the cef_urlrequest_t static factory functions. 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 cef_browser_host_t static factory
// function and all other request context objects will be ignored.
