--- Comment #3 from Konstantin Kolinko <knst.koli...@gmail.com> --- (In reply to Jeremy Boynes from comment #0) > The HTML5 specification is specifying that cookie values may contain > characters that are not part of US-ASCII or ISO-8859-1 and that those > codepoints should be UTF-8 encoded for display. > > http://www.w3.org/html/wg/drafts/html/master/single-page.html#cookie > What is the exact wording? The above link is broken - there is no "cookie" anchor in the current version of that document. All I see are references to [COOKIES] document (#refsCOOKIES anchor) = RFC 6265. http://tools.ietf.org/html/rfc6265 RFC 6265 does not allow non-ascii characters in cookie value in Set-Cookie header. Citing from its Chapter 4.1.1. Set-Cookie / Syntax, set-cookie-header = "Set-Cookie:" SP set-cookie-string set-cookie-string = cookie-pair *( ";" SP cookie-av ) cookie-pair = cookie-name "=" cookie-value cookie-name = token cookie-value = *cookie-octet / ( DQUOTE *cookie-octet DQUOTE ) cookie-octet = %x21 / %x23-2B / %x2D-3A / %x3C-5B / %x5D-7E ; US-ASCII characters excluding CTLs, ; whitespace DQUOTE, comma, semicolon, ; and backslash The cookie-value is limited to US-ASCII, even when quoted. At the same time, attributes (cookie-av) do not have such limitation and as such may be UTF-8: path-av = "Path=" path-value path-value = <any CHAR except CTLs or ";"> For reference, the place where UTF-8 is mentioned in RFC 6265 is in chapter 5.4. The Cookie Header. Citing: NOTE: Despite its name, the cookie-string is actually a sequence of octets, not a sequence of characters. To convert the cookie-string (or components thereof) into a sequence of characters (e.g., for presentation to the user), the user agent might wish to try using the UTF-8 character encoding [RFC3629] to decode the octet sequence. This decoding might fail, however, because not every sequence of octets is valid UTF-8. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
