-// 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. |
