是否可以使用一个Set-Cookie设置多个Cookie？ [英] Is it possible to set more than one cookie with a single Set-Cookie?

问题描述

一个HTTP Set-Cookie指令只能保存一个Cookie，是不是？我的意思是，一个 name = value 对？

One HTTP Set-Cookie directive can only hold one cookie, is it right? I mean, one single name=value pair?

推荐答案

Cookie的规范（请参阅

The original cookie specification of Netscape (see this cached version) does not say anything about listing multiple cookie declarations.

但是从 定义的Set-Cookie a href =http://tools.ietf.org/html/rfc2109 =nofollow noreferrer> RFC 2109 允许以逗号分隔的Cookie声明列表：

But as of Set-Cookie as defined by RFC 2109 allows a comma separated list of cookie declaration:

非正式地，Set-Cookie响应头包括令牌Set-Cookie :,后面是一个或多个cookie的逗号分隔列表。每个Cookie以NAME = VALUE对开头，后跟零个或多个分号分隔的属性值对。

Informally, the Set-Cookie response header comprises the token Set-Cookie:, followed by a comma-separated list of one or more cookies. Each cookie begins with a NAME=VALUE pair, followed by zero or more semi-colon-separated attribute-value pairs.

适用于 RFC 2965 定义的 Set-Cookie2 ：

The same applies to Set-Cookie2 as defined by RFC 2965:

非正式地，Set-Cookie2响应头包括令牌Set-Cookie2 :,后面是一个或多个cookie的逗号分隔列表。每个Cookie以NAME = VALUE对开头，后跟零个或多个分号分隔的属性值对。

Informally, the Set-Cookie2 response header comprises the token Set-Cookie2:, followed by a comma-separated list of one or more cookies. Each cookie begins with a NAME=VALUE pair, followed by zero or more semi-colon-separated attribute-value pairs.

大多数用户代理仍然遵循Netscape的原始规范，我宁愿建议只使用自己的 Set-Cookie 头字段声明每个cookie。

But since most user agents still follow Netscape’s original specification, I would rather suggest to just declare each cookie with its own Set-Cookie header field.

也是最新的 RFC 6265 反映的内容：

This is also what the latest RFC 6265 reflects:

源服务器不应将多个Set-Cookie头字段折叠为
a单个头字段。用于折叠HTTP头
字段（即，如[RFC2616]中定义的）的通常机制可以改变
的Set-Cookie头字段的语义，因为使用％x2C（，）字符
由Set-Cookie以与此类折叠冲突的方式。

Origin servers SHOULD NOT fold multiple Set-Cookie header fields into a single header field. The usual mechanism for folding HTTP headers fields (i.e., as defined in [RFC2616]) might change the semantics of the Set-Cookie header field because the %x2C (",") character is used by Set-Cookie in a way that conflicts with such folding.
