performance - 目录斜杠重定向？这还会发生吗？

Question

我在看一篇文章referenced by Jeff Atwood关于 Yahoo's "Best Practices" for speeding up a website ，我注意到了这个小 gem :

One of the most wasteful redirects happens frequently and web developers are generally not aware of it. It occurs when a trailing slash (/) is missing from a URL that should otherwise have one. For example, going to http://astrology.yahoo.com/astrology results in a 301 response containing a redirect to http://astrology.yahoo.com/astrology/ (notice the added trailing slash). This is fixed in Apache by using Alias or mod_rewrite, or the DirectorySlash directive if you're using Apache handlers.

这还会发生吗？随着网络的发展，这篇文章已经很老了。我想我多年来一直在这样做。我想我最近没有注意到这种情况发生，但话说回来，我从来没有真正看过。这是 Apache 的东西吗？ IIS 7 会这样做吗？

我很害怕。抱着我。

尝试一下!

以下是一些从终端运行的截断请求。

curl -I  http://astrology.yahoo.com/astrology

HTTP/1.0 301 Moved Permanently
Date: Tue, 21 Jun 2011 13:24:24 GMT
Location: http://shine.yahoo.com/astrology/


curl -I http://wordpress.org/extend

HTTP/1.0 301 Moved Permanently
Server: nginx
Date: Tue, 21 Jun 2011 13:26:17 GMT
Location: http://wordpress.org/extend/

尽管 IIS 似乎以另一种方式做到了:

curl -I http://www.iis.net/overview

HTTP/1.0 200 OK
Server: Microsoft-IIS/7.0

curl -I http://www.iis.net/overview/

HTTP/1.0 301 Moved Permanently
Location: http://www.iis.net/overview

猜猜这取决于您如何配置它，但这绝对是需要优化的东西。
