→History view
Redirect information will be stored in the transition type of each visit. The current history API only has a boolean flag for redirects. It would be nice to differentiate permanent and temporary redirects, we will have to look into if this information is available from the docshell.
=== History view View ===
Coalescing redirefcts will be an optional portion of history queries, so callers can get the raw visit data if desired.
When queries for visited web pages are done, it is less clear what to do. Since redirects can change temporally, it may not be clear which redirect to use, and which pages deserve to be in the result. The ideal solution depends on what the expected use of non-visit-based history queries are, which is not yet clear. One solution is to not coalesce redirects at all. The other solution is, for a page X, if there is some (or perhaps, the most recent visit) that is a redirect to Y, substitute X with Y. This will be wrong if X's redirect changes, but this should handle most cases.
=== Bookmark Queries ===
In the history view or in the main page if a "bookmark" toggle button is added, we will need to quickly answer the question "is this page or an equivalent page bookmarked?"
First, let us discard one case: when the page in question redirects to a bookmarked page. In this case, the user has specifically bookmarked the destination page and probably does not consider the source page to be the same. Furthermore, the source page's redirect may have changed, so the equivalence of the URLs may not even be true any more.
