其中化网页浏览器使用HTTP /默认1.1吗？ [英] Which webbrowsers use http/1.1 by default?

问题描述

任何人都有一个想法，我在哪里可以查找信息？我是pretty确保IE浏览器4具有使用HTTP 1.1参数的默认和使用HTTP 1.1通过代理连接关。这里得到此信息。我假设以后的版本将有使用HTTP 1.1上了。如何旧版本的IE？如何火狐，歌剧，Safari浏览器等？

Anyone have an idea where can I look up that information? I'm pretty sure that IE 4 has the "Use HTTP 1.1" parameter on by default and the "Use HTTP 1.1 through proxy connections" off. Got this information from here. I assume the later versions would have "Use HTTP 1.1" on too. How about older versions of IE? How about Firefox, Opera, Safari etc?

推荐答案

所有常用的桌面浏览器（网景/ Mozilla浏览器，IE浏览器等）在过去的10 - 13年支持HTTP / 1.1。 Internet浏览器3.0和Netscape 2.0的支持它可以追溯到至少1996年（维基百科同意这一）。

All common desktop browsers (Netscape/Mozilla, Internet Explorer, et al) in the last 10-13 years support HTTP/1.1. Internet Explorer 3.0 and Netscape 2.0 supported it as far back as at least 1996 (Wikipedia agrees with this).

特别需要注意的是，HTTP / 1.1是必需的HTTP Host头，如果你想在一个单一IP地址服务于不同的领域不同的网站，这是必需的。因此，如果一个HTTP客户端不支持它，用户就无法访问许多网站。

Of particular note is that HTTP/1.1 is required for the HTTP HOST header, which is required if you want to serve different websites for different domains on a single IP address. As such if an HTTP client didn't support it, the user would be unable to access many websites.

我遇到了一个老的智能手机浏览器并不支持大约9年前，但这是最后一个例子我能想到的在这里我甚至听说，没有一个HTTP客户端的。

I encountered an old smartphone browser that didn't support it about 9 years ago, but that's the last example I can think of where I'd even heard of an HTTP client that didn't.

我会说，缺乏对HTTP客户端支持/ 1.1并不需要成为一个真正的考虑今天，即使你做一些很深奥的（虽然我还记得它是一个技术支持的头痛在10年前，试图让人们从Netscape 1.x的升级）。

I'd say that lack of client support for HTTP/1.1 does not need to be a real consideration today even if your doing something fairly esoteric (although I still remember it being a technical support headache over 10 years ago, trying to get people to upgrade from Netscape 1.x).

如果你正在写你可能要考虑一下代理服务器，但实际上即便如此，我看不到它造成任何现实世界的问题，因为它是如此重要的现代浏览。如果有人正在运行的浏览器如旧（或限制）的马赛克1.0或Netscape 1.1，然后他们可能有更大的问题访问内容。

If you are writing a proxy you might want to think about it, but really even then I can't see it causing any real world problems as it's so fundamental to modern browsing. If someone is are running a browser as old (or as limited) as Mosaic 1.0 or Netscape 1.1 then they probably have bigger problems accessing content.
