为什么 Apache mod_rewrite 重写我的 URL 两次？

Question

我需要将/admin/page/create URL 重写为/backend/www/index.php/page/create，所以我使用下一个 Apache 重写规则和条件：

RewriteCond %{REQUEST_URI} !-f
RewriteCond %{REQUEST_URI} !-d
RewriteCond %{REQUEST_URI} !backend\/www

RewriteRule admin\/(.*)$ backend/www/index.php/$1 [NS,L]

但是，检查重写日志，我看到 Apache 正确地重写了 URL，但最后它执行了额外的重写，考虑到 /page/create URL，它不匹配任何条件，所以它失败并且我收到 “没有指定输入文件。”错误。

如何防止 Apache 执行额外的重写？我使用了NS 标志和RewriteCond %{IS_SUBREQ} f 条件，它也执行子请求。

谢谢！

Answer 1

好吧，我终于用一种变通方法解决了这个问题。首先我尝试了these solutions，但是子请求一次又一次地执行，并且像以前一样重写失败。

使用 mod_rewrite，如果您将规则放在 .htaccess 或全局配置（httpd.conf、Virtualhost 配置等）中，则存在细微差别。子请求是其中的区别之一。只需将我上面提到的相同规则放在 Virtualhost 配置文件中而不是 .htaccess 中，子查询就会停止，一切都会像魅力一样开始工作。

我推荐这篇有用的帖子，以便在尝试解决任何相关问题之前充分了解 mod_rewrite 的内部结构：http://net.tutsplus.com/tutorials/other/a-deeper-look-at-mod_rewrite-for-apache/

我只是想在这里放弃我的经验，以防有人达到我所做的相同点：

我遇到了同样的问题。我尝试了每一个答案。每一个解决方案。达到我可以说“我真的完全理解重写引擎”的水平。但没有任何效果。我的网址仍在更改并显示查询字符串。
在某个时刻，我说：“这很可能是不可能的。一定是别的东西”。然后我尝试使用 WGET 而不是浏览器 (firefox) 获取 URL。 我做到了：

wget -qSO http://MY-THING

然后我意识到服务器上没有任何内容表示我在浏览器地址栏中看到的 URL。更好的是，日志文件中没有任何内容！

那么...它如何以及为什么会发生变化？显而易见的答案是“浏览器” 我尝试了另一个浏览器（chrome）并且可以工作！ 所以我所做的就是使用"forget this site" 选项清除历史记录，让每个人都开心。

现在我不知道我什么时候修好的。可能是 -Multiviews 的东西，或者规则的标志，或者 INTERNAL REDIRECT 部分......我真的不知道。但可能没有解决方案。
