I presume MeiK wants to use BaseCookie to parse the Set-Cookie header field, as in
>>> BaseCookie('Hello=World; Expires=Thu, 31 Jan 2019 05:56:00 GMT;')
<BaseCookie: Hello='World'>
>>> BaseCookie('Hello=World; Expires=Thu,31 Jan 2019 05:56:00 GMT;')
<BaseCookie: >
Karthikeyan, if you meant the “sane-cookie-date” format (https://tools.ietf.org/html/rfc6265#page-9), that is just the IETF’s recommended date format. I suspect MeiK is trying to _parse_ the date rather than generate it, in which case the procedure in <https://tools.ietf.org/html/rfc6265#section-5.1.1> may be more relevant. Spaces and commas are both treated as delimiters, so the problematic Expires attribute should parse fine.
BTW, this special handling of Set-Cookie attributes like Expires is not documented, though it does seem intentional. According to the documentation they should be treated as new Morsels.
