Apache 2.4根/匹配项的重写规则，但根据重写调试日志被忽略（索引文件的子请求仍在继续）

编辑：我向Apache报告了这一点，它确实是一个bug，已在2.4.9中修复，请参阅。。。对于Ubuntu，有一个更新的PPA。对于那些无法升级或不想编译的用户，我在下面发布了一个解决方案

这已经让我发疯了。Ubuntu 14.04上的Apache 2.4.7。重写规则很简单：

RewriteCond %{REQUEST_URI} ^/?$
RewriteRule ^ /web/wp-content/cache/page_enhanced/HOSTNAME/_index.html [L]

基本上，我想为/提供一个.html文件。.html文件存在，如果直接请求，可以正常提供。正如您在下面的调试日志中所看到的（

LogLevel alert rewrite:trace6

，在服务器配置中），cond on/确实匹配（

initial

），但Apache继续（

subreq

）并未能匹配/index.html、/index.cgi、/index.pl和/index.php，最后提供/index.php

这是预料不到的<代码>[L]应该阻止Apache在找到匹配项后继续

我可以确认Apache 2.2中不存在此问题。这看起来像Apache2.4中的一个bug。。。还是我遗漏了什么

另外，另一件令人沮丧的事情是，这似乎只是/的问题。同样的规则只适用于子目录（即，

RewriteCond%{REQUEST_URI}^/subdr/？$

）也可以按照2.4中的预期工作

有什么线索吗？

目前，我的（丑陋的）解决方案是：

RewriteCond %{REQUEST_URI} ^(/index.\w+|/)?$
RewriteRule ^ /web/wp-content/cache/page_enhanced/HOSTNAME/_index.html [L]

换句话说，我将匹配所有可能的/index.*以及/。前者应该是不必要的，在我的情况下，它使我的设置复杂化，因为index.php应该匹配其他规则，所以我也需要解决这个问题

请注意，此错误（？）仅发生在/。子目录的相同规则也适用，即：

RewriteCond %{REQUEST_URI} ^/subdir/?$
RewriteRule ^ /web/wp-content/cache/page_enhanced/HOSTNAME/subdir/_index.html [L]

很好用
