I can't seem to reproduce this on emacs-26 or master:
0. HOME=$(mktemp -d) emacs -Q
1. (let ((get (lambda ()
(with-current-buffer
(url-retrieve-synchronously "https://gnu.org")
(message "%s" url-http-end-of-headers)))))
(dotimes (_ 3) (funcall get))
(setq url-automatic-caching t
url-cache-expire-time (* 6 3600))
(dotimes (_ 3) (funcall get)))
2. C-x C-e
