Summary: X-Vary-Options header should be configurable, not sent to users Product: MediaWiki Version: unspecified Platform: All OS/Version: All Status: NEW Severity: minor Priority: Normal Component: Page rendering AssignedTo: wikibugs-l@lists.wikimedia.org ReportedBy: greenrea...@hotmail.com MediaWiki sends a custom X-Vary-Options header on responses. The reason for doing so is described here: http://www.mail-archive.com/squid-...@squid-cache.org/msg07066.html An example: X-Vary-Options: Accept-Encoding;list-contains=gzip,Cookie;string-contains=ruToken;string-contains=ruLoggedOut;string-contains=ru_session\r\n This header helps patched caches. However for those sites which don't have that patch applied, or who don't use Squid at all - i.e. pretty much everyone outside Wikimedia - this feature just adds around 137 uncompressed bytes of useless padding per request. This header should be optional, and off by default, unless/until this patch is accepted upstream in Squid. FWIW, I also feel this header should also be stripped out from Wikimedia responses going to end-users (==if there is no Via: header in the request), otherwise you're needlessly sending them ~260 uncompressed bytes per request: X-Vary-Options: Accept-Encoding;list-contains=gzip,Cookie;string-contains=enwikiToken;string-contains=enwikiLoggedOut;string-contains=enwiki_session;string-contains=centralauth_Token;string-contains=centralauth_Session;string-contains=centralauth_LoggedOut This would presumably involve changing the Squid patch itself. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
