(also posted on Mediawiki.org on API talk:Login [1]) Hi, My application, WPCleaner [2] works fine on Wikimedia wikis (Wikipedia, Wiktionary, ...), but my attempts to make it work on Waze wiki [3] have failed for now. I don't understand why login doesn't work on Waze wiki. Would someone have an idea about this problem ? The first call to the login method for waze wiki returns a "NeedToken" answer as usual, with a session id in the answer and a wikidb_session cookie. When I call the login method a second time, with wikidb_session cookie set and the token, the answer from waze wiki is again a "NeedToken" with a different session id and wiki_session cookie. Apart from this, the only difference that I noticed is the cookie name: enwikiSession for enwiki, wikidb_session for waze (no uppercase letter and an underscore). Here's what my logs are saying when calling enwiki login: POST https://en.wikipedia.org/w/api.php?action=login&lgname=NicoVTest&fo… Request header:Accept-Encoding: gzip Request header:User-Agent: WPCleaner (+ http://en.wikipedia.org/wiki/User:NicoV/Wikipedia_Cleaner/Documentation) Request header:Host: en.wikipedia.org Request header:Content-Length: 60 Request header:Content-Type: application/x-www-form-urlencoded Response header:Server: nginx/1.1.19 Response header:Date: Fri, 11 Jul 2014 21:58:05 GMT Response header:Content-Type: text/xml; charset=utf-8 Response header:Content-Length: 159 Response header:Connection: keep-alive Response header:X-Content-Type-Options: nosniff Response header:Cache-control: private Response header:Set-Cookie: enwikiSession=XXXXXX; path=/; secure; HttpOnly Response header:X-Frame-Options: SAMEORIGIN Response header:Content-Encoding: gzip Response header:Vary: Accept-Encoding Response header:X-Varnish: 2249630267, 3978847279, 3259701709 Response header:Via: 1.1 varnish, 1.1 varnish, 1.1 varnish Response header:Accept-Ranges: bytes Response header:Age: 0 Response header:X-Cache: cp1068 miss (0), amssq53 miss (0), amssq43 frontend miss (0) Response header:Set-Cookie: GeoIP=XXXXXX; Path=/; Domain=.wikipedia.org POST https://en.wikipedia.org/w/api.php?action=login&lgname=NicoVTest&fo… Request header:Accept-Encoding: gzip Request header:User-Agent: WPCleaner (+ http://en.wikipedia.org/wiki/User:NicoV/Wikipedia_Cleaner/Documentation) Request header:Host: en.wikipedia.org Request header:Cookie: $Version=0; enwikiSession=XXXXXX; $Path=/ Request header:Cookie: $Version=0; GeoIP=FR:Clamart:48.8000:2.2667:v4; $Path=/; $Domain=.wikipedia.org Request header:Cookie2: $Version="1" Request header:Content-Length: 101 Request header:Content-Type: application/x-www-form-urlencoded Responses headers...
