有以下规则

<code><ifmodule mod_rewrite.c>
  RewriteEngine On
  RewriteOptions AllowAnyURI
  Options +FollowSymLinks 
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ /index.php/$1 [QSA,PT,L]
</ifmodule></code>

我需要如下的URL模式:/resource:36

不重写就没问题：/index.php/resource:36
我找到了如下参考

mod_rewrite

AllowAnyURI

When RewriteRule is used in VirtualHost or server context with version 2.2.22 or later of httpd, mod_rewrite will only process the rewrite rules if the request URI is a URL-path. This avoids some security issues where particular rules could allow "surprising" pattern expansions (see CVE-2011-3368 and CVE-2011-4317). To lift the restriction on matching a URL-path, the AllowAnyURI option can be enabled, and mod_rewrite will apply the rule set to any request URI string, regardless of whether that string matches the URL-path grammar required by the HTTP specification.
Available in Apache HTTP Server 2.4.3 and later.

是我理解错了么？
PS:sourceforge有这样格式的url：
https://sourceforge.net/directory/natlanguage:chinesesimplified/os:windows/

补充：
类似如下的重写机制，个人亲测，在Apache的URL检测时期就返回403了，根本轮不到url重写模块

<code>RewriteRule ^(.*)$ index.php?str=$1 [QSA,PT,L]</code>

回复内容：

<code>RewriteRule ^(.*)$ index.php?str=$1 [QSA,PT,L]</code>

思路大概是这样的，你写正则表达式的规则从URL抓取字符串，转发到index.php，当成一个参数，然后你自己写逻辑去解析这个字符串

所以你重写规则应该改成类似

<code>RewriteRule ^(.*)$ index.php?str=$1 [QSA,PT,L]</code>

然后尝试在str中解析，然后内部路由到具体类、方法执行再响应
