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 WebContents. 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 WebContents 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.
