+If cookie middleware is enabled, ``get_cookiejar(response_or_request)`` method added to spider:
+
+.. class:: scrapy.Spider
+
+    ...
+
+    .. method:: get_cookiejar(spider, response_or_request)
+
+      Returns ``scrapy.http.cookies.CookieJar`` cookiejar object based on  :reqmeta:`cookiejar` value of ``response_or_request`` argument
+
+      :param response_or_request: request or response object where target session/cookiejar object used or planned to use
+      :type response_or_request: :class:`~scrapy.Request` or :class:`~scrapy.Response` object
+
+      Technically this is short cut to ``request.meta.get('cookiejar')`` or ``response.request.meta.get('cookiejar')`` if ``response_or_request`` is :class:`~scrapy.Response`
+
+      It allows a bit easier access to cookiejar object:
+
+      .. code-block:: python
+
+          ...
+          self.logger.info(self.get_cookiejar(response))  # scrapy.http.cookies.CookieJar object
+          self.logger.info(self.get_cookiejar(response).jar)  # http.cookiejar object
+          locale_cookie = (
+              self.get_cookiejar(response).jar._cookies["quotes.toscrape.com"]["/"].get("session")
+          )
+
+Known use cases where direct access to cookiejar objects can be useful:
+
+1. Modifying specific cookie value (as provided on example code sample above).
+2. Delete cookiejar. On some cases this can re-initialise session.
+
+.. warning:: ``http.cookiejar`` object from python standart lib https://docs.python.org/3/library/http.cookies.html doesn't provide option to individually access/modify specific cookie values. It is possible to change it only using it's private attributes as provided on code sample above.
