+    The passed-in cookie string should be stringified via JSON.stringify() (in
+    the case of multiple cookie headers sent in an array) and encoded via
+    encodeURIComponent, otherwise `parse_qsl` will split on any semicolons
+    (used by the Request.GET property getter). Note that values returned by
+    Request.GET will decode any percent-encoded sequences sent in a GET param
+    (which may or may not be surprising depending on what you're doing).
+
+    Note: here we don't use Response.delete_cookie() or similar other methods
+    in this resources directory because there are edge cases that are impossible
+    to express via those APIs, namely a bare (`Path`) or empty Path (`Path=`)
+    attribute. Instead, we pipe through the entire cookie and append `max-age=0`
+    to it.
