On pages where an application silently redirects a user away, it may be confusing or difficult to debug because the toolbar may no errors, the result is not what the developer expected, and may not think to check redirects.

As an example, a developer tries to login from /login, it fails, but they don't know why because the current page load (for /login) shows all green and has no log messages. They would have to know to go through the profiler to find the login_check request and look at the log there.

Further, even if they know that the got looped around, it would be much more convenient if the toolbar provided a link to those profiler pages instead of needing to go look it up.

My proposal is a toolbar tab similar to (or perhaps an expansion of) the AJAX tab which lists the result, execution time, and profiler link to pages that were loaded between the last page I was on, and the one I'm currently on.

I'm not familiar with the internals of the toolbar so am unsure about how this might be implemented, but perhaps by looking at the Referrer and matching that to recent profiler logs?
