In rare occasion, a timing issue could cause uBO to redirect
to a web accessible resource meant to be used for another
network request. This is a regression introduced with the
following commit:
- 2e5d32e967
Additionally, I identified another issue which would cause
cached redirection to fail when a cache entry with redirection
to a web accessible resource was being reused, an issue which
could especially affect pages which are generated dynamically
(i.e. without full page reload).
