18908	Can't set multiple cookies with the same name but different domains/paths	ludwig.haehne	nobody	"There is no way to set cookies with the same name for multiple domains or paths in the same response.

The following code only sets the second cookie:

{{{
response.set_cookie(""alice"", ""123"", domain='sub.example.com')
response.set_cookie(""alice"", ""456"", domain='example.com')
}}}

It makes sense because Django uses a dictionary for storing cookies:

{{{
self.cookies[key] = value
}}}

Therefore, Django cannot set multiple cookies with the same name but different domains or paths in the same response. [http://tools.ietf.org/html/rfc2965 RFC2965] is not completely clear if this should be possible but this article [http://www.nczonline.net/blog/2009/05/05/http-cookies-explained/] suggests that it should be:

  This cookie has four identifying characteristics: the cookie '''name''', the '''domain''', the '''path''', and the '''secure''' flag. In order to change the value of this cookie in the future, another Set-Cookie header must be sent using the same cookie name, domain, and path.
