+
+# Specifies if/how Opencast is used as a fallback when requests cannot be
+# authorized by octoka itself (purely based on JWT).
+#
+# - "none": no fallback, Opencast is not contacted.
+# - "head": an HTTP HEAD request is sent to Opencast, with the same URI
+#   and headers as the incoming request. Octoka's behavior depends on
+#   Opencast's response:
+#   - 2xx: treat request as allowed
+#   - 404: respond with 404
+#   - 401: respond with 401, forwarding the www-authenticate header
+#   - everything else: treat as forbidden
+# - "get": like "head", but with HTTP method GET. This exists only for
+#   older Opencast which had incorrect responses to HEAD requests. If you
+#   use this, set `x.accel.redirect` in OC, in order to not send the file.
+#   This option will get deprecated and removed in the future.
