-// Cross-Site Navigations
-//
-// If a TabContents is told to navigate to a different web site (as determined
-// by SiteInstance), it will replace its current RenderViewHost with a new
-// RenderViewHost dedicated to the new SiteInstance. This works as follows:
-//
-// - Navigate determines whether the destination is cross-site, and if so,
-// it creates a pending_render_view_host_ and moves into the PENDING
-// RendererState.
-// - The pending RVH is "suspended," so that no navigation messages are sent to
-// its renderer until the onbeforeunload JavaScript handler has a chance to
-// run in the current RVH.
-// - The pending RVH tells CrossSiteRequestManager (a thread-safe singleton)
-// that it has a pending cross-site request. ResourceDispatcherHost will
-// check for this when the response arrives.
-// - The current RVH runs its onbeforeunload handler. If it returns false, we
-// cancel all the pending logic and go back to NORMAL. Otherwise we allow
-// the pending RVH to send the navigation request to its renderer.
-// - ResourceDispatcherHost receives a ResourceRequest on the IO thread. It
-// checks CrossSiteRequestManager to see that the RVH responsible has a
-// pending cross-site request, and then installs a CrossSiteEventHandler.
-// - When RDH receives a response, the BufferedEventHandler determines whether
-// it is a download. If so, it sends a message to the new renderer causing
-// it to cancel the request, and the download proceeds in the download
-// thread. For now, we stay in a PENDING state (with a pending RVH) until
-// the next DidNavigate event for this TabContents. This isn't ideal, but it
-// doesn't affect any functionality.
-// - After RDH receives a response and determines that it is safe and not a
-// download, it pauses the response to first run the old page's onunload
-// handler. It does this by asynchronously calling the OnCrossSiteResponse
-// method of TabContents on the UI thread, which sends a ClosePage message
-// to the current RVH.
-// - Once the onunload handler is finished, a ClosePage_ACK message is sent to
-// the ResourceDispatcherHost, who unpauses the response. Data is then sent
-// to the pending RVH.
-// - The pending renderer sends a FrameNavigate message that invokes the
-// DidNavigate method. This replaces the current RVH with the
-// pending RVH and goes back to the NORMAL RendererState.
