HTTPbis - bis是什么意思？ [英] HTTPbis - what does bis mean?
问题描述
我经常看到协议版本附加了bis（例如v.34bis或httpbis）。
I've often seen "bis" appended to versions of protocols (eg v.34bis or httpbis).
bis是什么意思或代表什么？
What does "bis" mean or stand for?
我认识的电信工程师认为它原产地可能是法国人。
A telecom engineer I know thinks it might be French in origin.
推荐答案
正如其他人已经说过的那样，bis来自两次或重复。它用于表示某事物的第二个变体（虽然通常只有很小的变化但不保证新名称）。
As others have already said, "bis" comes from "twice" or "repeat". It's used to indicate a second variant of something (although usually with only minor variations that don't warrant a new name).
在HTTP的上下文中，HTTPbis是负责提炼HTTP的工作组的名称。根据其章程：
In the context of HTTP, HTTPbis is the name of the working group in charge of refining HTTP. According to its charter:
HTTP是目前
互联网上最成功和最广泛使用的协议之一。但是，它的规范有几个编辑
问题。此外，经过多年的实施和扩展，
几个含糊不清已经变得明显，削弱了互操作性
以及轻松实现和使用HTTP的能力。
HTTP is one of the most successful and widely-used protocols on the Internet today. However, its specification has several editorial issues. Additionally, after years of implementation and extension, several ambiguities have become evident, impairing interoperability and the ability to easily implement and use HTTP.
工作组将RFC2616改进为：
The working group will refine RFC2616 to:
- 合并勘误表和更新（例如，参考资料，IANA注册管理机构，ABNF）
- 修复导致对规范产生误解的编辑问题
- 澄清一致性要求
- 消除影响互操作性的已知歧义
- 澄清现有的可扩展性方法
- 删除或弃用那些未广泛实施且过度影响互操作性的功能
- 必要时，添加实施建议
- 记录HTTP的安全属性及其相关机制（例如，基本和摘要式身份验证，cookie，TLS）以用于常见应用程序
- Incorporate errata and updates (e.g., references, IANA registries, ABNF)
- Fix editorial problems which have led to misunderstandings of the specification
- Clarify conformance requirements
- Remove known ambiguities where they affect interoperability
- Clarify existing methods of extensibility
- Remove or deprecate those features that are not widely implemented and also unduly affect interoperability
- Where necessary, add implementation advice
- Document the security properties of HTTP and its associated mechanisms (e.g., Basic and Digest authentication, cookies, TLS) for common applications
它还将包含来自RFC
2617的通用认证框架，而不会废弃或更新该规范的定义
的基本和摘要方案。
It will also incorporate the generic authentication framework from RFC 2617, without obsoleting or updating that specification's definition of the Basic and Digest schemes.
最后，它将包含RFC 2817的相关部分（特别是
，CONNECT方法和使用升级的建议），所以
表示该规范可以移至历史状态。
Finally, it will incorporate relevant portions of RFC 2817 (in particular, the CONNECT method and advice on the use of Upgrade), so that that specification can be moved to Historic status.
这样做时，应考虑：
- 实施者体验
- 证明使用HTTP
- 对现有实施和部署的影响
工作组不得引入新版本的HTTP，并且
不应向HTTP添加新功能。工作组的任务不是生成
新方法，标头或扩展机制，但如果需要，可能会引入新的
协议元素，作为修改现有
功能的一部分，这已证明是有问题的。
最后一段（强调我的）解释了为什么他们在这种情况下使用了bis，因为他们明确地说我想要一个新版本。
The last paragraph (emphasis mine) explains why they've used "bis" in this context, since they explicitly don't want a new version.
