Some research to report:

In all cases, webView.request.URL is the previous page's URL (or empty) during the didStartLoad callback.

When loading a page with a redirect:
1. shouldStartLoading (requestURL is target page)
2. didStartLoading
3. shouldStartLoading (requestURL is redirect target)
4. didFinishLoad (request.URL is redirect target)

** Note the lack of a second didStartLoading **


When loading a page with iframes:
1. shouldStartLoading (requestURL is main page)
2. didStartLoading
3. shouldStartLoading (requestURL is one of the iframes)
4. didStartLoading
5. didFinishLoad
6. didFinishLoad

** Note there is no way to distinguish which didFinishLoad maps to which didStartLoad **


Loading a page by calling window.history.go(-1):
1. didStartLoading
2. didFinishLoad

** Note the lack of a shouldStartLoading call **


Loading a page by calling location.reload()
1. shouldStartLoading
2. didStartLoading
3. didFinishLoad

> I'm seeing an intermittent issue where a FileTransfer download appears to do nothing at all. The file never downloads, the call returns without error, and neither the success or error callbacks are ever invoked. Additionally, the onprogress function on the FileTransfer instance is never called.
> I've seen this problem on iOS (simulator and device), but I have not tried other devices yet.
> I haven't been able to reduce it a clean testcase, but so far, the only pattern I've seen is that it only occurs when I request the download very shortly after creating a directory.
