| 106 | // Cross-Site Navigations |
| 107 | // |
| 108 | // If a WebContentsImpl is told to navigate to a different web site (as |
| 109 | // determined by SiteInstance), it will replace its current RenderViewHost with |
| 110 | // a new RenderViewHost dedicated to the new SiteInstance. This works as |
| 111 | // follows: |
| 112 | // |
| 113 | // - Navigate determines whether the destination is cross-site, and if so, |
| 114 | // it creates a pending_render_view_host_. |
| 115 | // - The pending RVH is "suspended," so that no navigation messages are sent to |
| 116 | // its renderer until the onbeforeunload JavaScript handler has a chance to |
| 117 | // run in the current RVH. |
| 118 | // - The pending RVH tells CrossSiteRequestManager (a thread-safe singleton) |
| 119 | // that it has a pending cross-site request. ResourceDispatcherHost will |
| 120 | // check for this when the response arrives. |
| 121 | // - The current RVH runs its onbeforeunload handler. If it returns false, we |
| 122 | // cancel all the pending logic. Otherwise we allow the pending RVH to send |
| 123 | // the navigation request to its renderer. |
| 124 | // - ResourceDispatcherHost receives a ResourceRequest on the IO thread for the |
| 125 | // main resource load on the pending RVH. It checks CrossSiteRequestManager |
| 126 | // to see that it is a cross-site request, and installs a |
| 127 | // CrossSiteResourceHandler. |
| 128 | // - When RDH receives a response, the BufferedResourceHandler determines |
| 129 | // whether it is a download. If so, it sends a message to the new renderer |
| 130 | // causing it to cancel the request, and the download proceeds. For now, the |
| 131 | // pending RVH remains until the next DidNavigate event for this |
| 132 | // WebContentsImpl. This isn't ideal, but it doesn't affect any functionality. |
| 133 | // - After RDH receives a response and determines that it is safe and not a |
| 134 | // download, it pauses the response to first run the old page's onunload |
| 135 | // handler. It does this by asynchronously calling the OnCrossSiteResponse |
| 136 | // method of WebContentsImpl on the UI thread, which sends a SwapOut message |
| 137 | // to the current RVH. |
| 138 | // - Once the onunload handler is finished, a SwapOut_ACK message is sent to |
| 139 | // the ResourceDispatcherHost, who unpauses the response. Data is then sent |
| 140 | // to the pending RVH. |
| 141 | // - The pending renderer sends a FrameNavigate message that invokes the |
| 142 | // DidNavigate method. This replaces the current RVH with the |
| 143 | // pending RVH. |
| 144 | // - The previous renderer is kept swapped out in RenderViewHostManager in case |
| 145 | // the user goes back. The process only stays live if another tab is using |
| 146 | // it, but if so, the existing frame relationships will be maintained. |
