// HOW REDIRECT TRACKING WORKS
// ---------------------------
// When we get an AddDocumentRedirect message, we store the redirect in
// our mRecentRedirects which maps the destination URI to a source,time pair.
// When we get a new URI, we see if there were any redirects to this page
// in the hash table. If found, we know that the page came through the given
// redirect and add it.
//
// Example: Page S redirects throught R1, then R2, to give page D. Page S
// will have been already added to history.
// - AddDocumentRedirect(R1, R2)
// - AddDocumentRedirect(R2, D)
// - AddURI(uri=D, referrer=S)
//
// When we get the AddURI(D), we see the hash table has a value for D from R2.
// We have to recursively check that source since there could be more than
// one redirect, as in this case. Here we see there was a redirect to R2 from
// R1. The referrer for D is S, so we know S->R1->R2->D.
//
// Alternatively, the user could have typed or followed a bookmark from S.
// In this case, with two redirects we'll get:
// - MarkPageAsTyped(S)
// - AddDocumentRedirect(S, R)
// - AddDocumentRedirect(R, D)
// - AddURI(uri=D, referrer=null)
// We need to be careful to add a visit to S in this case with an incoming
// transition of typed and an outgoing transition of redirect.
//
// Note that this can get confused in some cases where you have a page
// open in more than one window loading at the same time. This should be rare,
// however, and should not affect much.
