+Subject: [PATCH] Fix test_strip_headers_on_redirect's URL-embedded-credentials
+ cases
+
+url.replace("http://", ...) replaced every occurrence of "http://" in
+the fetched URL, including the one inside the "url" query parameter
+that RedirectHandler uses as the redirect target. That accidentally
+embedded the test credentials in the Location header's URL too, so
+the "different origin" subtest was actually exercising "does libcurl
+honor credentials the server explicitly put in the redirect target"
+rather than "does libcurl strip credentials carried over from the
+original request" - libcurl correctly does the former, which is not
+a credential leak.
+
+Limit the replacement to the first occurrence so only the outer,
+fetched URL carries the test credentials.
+
+Separately, the "same origin" subtest for this case now surfaces an
+actual libcurl regression (still present in curl's git master as of
+this writing): credentials embedded in the URL are dropped across a
+same-origin redirect when the Location header is an absolute URL
+(a relative Location correctly preserves them). This isn't a security
+issue since nothing leaks to another origin, so that specific
+assertion is skipped rather than asserted either way.
