Since http://code.google.com/p/chromium/issues/detail?id=7338 and https://bugzilla.mozilla.org/show_bug.cgi?id=479880 there is no clean way for a proxy or captive portal to get a web client to display an authentication dialog when user credentials expire while he is browsing on an https url. (to be sure, the previous methods were insecure and hackish but they existed because nothing better was available) The IETF finally set up to fix this problem and defined a standard HTTP error that lets access control equipments tell the web client authentication or re-authentication is needed and where the authentication form is located. http://tools.ietf.org/id/draft-nottingham-http-new-status-04.txt → <http://www.rfc-editor.org/queue2.html#draft-nottingham-http-new-status> (the spec is approved and in the queue for publication as RFC) Please add error 511 handling in git, so git users that try to access external git repositories over http can authenticate on the corporate proxy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
