Since 301 URL Tracker is basically defunct, I've uninstalled it and will be relying on Umbraco's built-in redirect management. That was that plan, anyway; it doesn't seem to be working.

Here's what I notice:

• I removed 301 URL Tracker, and confirmed the "InfoCaster" DLL's are no longer in my bin folder.
• Umbraco 7.5.6.
• The umbracoRedirectUrl table originally had 600+ entries, but I truncated that table yesterday and nothing new has shown up since.
• I have a few content finders and URL providers (see code below). I don't think that's an issue, as according to this page there is a ContentFinderByRedirectUrl content finder that I have not removed: https://our.umbraco.org/documentation/reference/routing/URL-Tracking/
• I have set disableRedirectUrlTracking="false" in umbracoSettings.config just to be certain it's not disabled by default.
• I have tried renaming, moving, and creating content nodes, and that has not created any entries in the umbracoRedirectUrl table. Similarly, nothing appears in the "Redirect URL Management" dashboard.
• The "Redirect URL Management" dashboard has no indication that redirect tracking is disabled.

Here's what shows up in my Umbraco log when I rename a content node:

Here's how I setup my content finders and URL providers in the application starting event:

// Content finder.
ContentFinderResolver.Current
    .InsertTypeBefore<ContentFinderByNiceUrl, MySiteContentFinder>();
ContentFinderResolver.Current.RemoveType<ContentFinderByNiceUrl>();

// 404 content finder.
ContentLastChanceFinderResolver.Current
    .SetFinder(new MySite404ContentFinder());

// URL provider.
UrlProviderResolver.Current.RemoveType<DefaultUrlProvider>();
UrlProviderResolver.Current.InsertType<MySiteUrlProvider>();

Those seem to work fine.

I have not found any reason why redirect tracking should not be working. Any ideas?
