class Profile;

// Monitors omnibox navigations in order to trigger behaviors that depend on
// successful navigations.
//
// Currently three such behaviors exist:
// (1) For single-word queries where we can't tell if the entry was a search or
//     an intranet hostname, the omnibox opens as a search by default, but this
//     class attempts to open as a URL via an HTTP HEAD request.  If successful,
//     displays an infobar once the search result has also loaded.  See
//     AlternateNavInfoBarDelegate.
// (2) Omnibox navigations that complete successfully are added to the
//     Shortcuts backend.
// (3) Omnibox searches that result in a 404 for an auto-generated custom
//     search engine cause the custom search engine to be deleted.
//
// Please see the class comment on the base class for important information
// about the memory management of this object.
