// There are two different kinds of NavigationClients, the request
// NavigationClient and the commit NavigationClient.
//
// ## Request NavigationClient ##
// Set if and only if the frame that initiated the navigation and the frame
// being navigated are both RenderFrameImpls in the same frame tree (i.e. the
// navigation does not ever go through a RenderFrameProxy). This has
// interesting implications for behavior differences between the two example
// frame trees below:
//
// a.com a.com
// ↓ ↓
// b.com example.a.com
//
// Assuming the standard site-per-process allocation policy, though (a.com) is
// cross-origin to both (b.com) and (example.a.com):
//
// - (a.com) performing a navigation in (b.com) *will not* create a request
// NavigationClient but
// - (a.com) performing a navigation in (example.a.com) *will* create a
// request
//
// Finally, note that the initiating RenderFrameImpl does *not* own the
// request NavigationClient. Rather, the RanderFrameImpl that the navigation
// *targets* is the RenderFrameImpl that owns the request NavigationClient.
//
// ## Commit NavigationClient ##
// Always set in the RenderFrameImpl that has been selected to commit a
// navigation. This selection happens when the NavigationRequest in the
// browser process reaches READY_TO_COMMIT.
//
// If a navigation will commit in the same RenderFrameImpl that owns the
// request NavigationClient, the request NavigationClient will be reused as
// the commit NavigationClient.
//
// ## Navigation Cancellation ##
// Cancellation is signalled by resetting the NavigationClient. This will
// eventually trigger a connection error in the browser process, which
// normally invokes NavigationRequest::OnRendererAbortedNavigation().
//
// However, once the NavigationRequest reaches READY_TO_COMMIT in the browser
// process, *only* the commit NavigationClient may cancel the navigation. This
// has several implications:
//
// - Web APIs like window.stop() and document() use AbortClientNavigation().
// However, once the NavigationRequest reaches READY_TO_COMMIT, cancellation
// is only respected if the navigation reuses the same RenderFrameImpl;
// otherwise, it is ignored.
//
// Note that using RenderDocument means that all cross-document navigations
// will use a provisional RenderFrameImpl: as such, all cross-document
// navigations with RenderDocument will ignore cancellation after
// READY_TO_COMMIT. This will be a compatibility issue for shipping
// RenderDocument: see https://crbug.com/763106 for historical context.
//
// - If the frame is owned by an <object> element, CommitFailedNavigation()
// will first trigger the fallback path (for remote frames, this
// unconditionally sends the RenderFallbackContentInParentProcess() IPC; for
// local frames, things are a bit more complicated...) before then
// unconditionally calling AbortCommitNavigation() to ignore the commit.
//

// frame. Don't bother sending a commit at all in that case.
