+Subject: [PATCH 10/10] Percent-encode the caret in the path
+
+The caret (^) is part of the path percent-encode set:
+
+"The path percent-encode set is a percent-encode set consisting of the query percent-encode set and U+003F (?), U+005E (^), U+0060 (`), U+007B ({), and U+007D (})."
+
+Until now, this character wasn't percent-encoded in the path likely due to a copy-paste error. This is mistake is fixed by adding LXB_URL_MAP_PATH to the lxb_url_map entry for the caret.
+
