 // in DidCommitProvisionalLoad.
+//
+// Standard:
+//   Follows network and cache protocols, e.g. using cached entries unless
+//   they are expired. Used in usual navigations.
+// BackForward:
+//   Uses cached entries even if the entries are stale. Used in history back and
+//   forward navigations.
+// Reload:
+//   Revalidates cached entries even if the entries are fresh. Used in usual
+//   reload.
+// ReloadMainResource:
+//   Revalidates a cached entry for the main resource if one exists, but follows
+//   protocols for other subresources. Blink internally uses this for the same
+//   page navigation. Also used in optimized reload for mobiles in a field
+//   trial.
+// ReplaceCurrentItem:
+//   Same as Standard, but replaces current navigation entry in the history.
+// InitialInChildFrame:
+//   Used in the first load for a subframe.
+// InitialHistoryLoad:
+//   Used in history navigation in a newly created frame.
+// ReloadBypassingCache:
+//   Bypasses any caches, memory and disk cache in the browser, and caches in
+//   proxy servers, to fetch fresh contents directly from the end server.
+//   Used in Shift-Reload.
