Descripción
*** Pendiente de traducción *** http.cookiejar.CookieJar deleted a stored cookie when a response carried an<br />
already expired Set-Cookie header for it, using the Domain and Path<br />
attributes from the header without consulting the cookie policy. A server<br />
could therefore delete cookies belonging to other domains from a shared<br />
cookie jar, such as the one used by urllib&#39;s HTTPCookieProcessor. The fix<br />
consults the cookie policy before an expired cookie may delete an existing<br />
one, as required by RFC 6265 section 5.3.
