htaccess选择性转发
这是一个有点独特的问题，我似乎无法在任何地方找到答案！我是处理 htaccess 文件的新手。这就是我想要做的，让我知道这是否可能：
我试图在有人直接访问某个目录时进行重定向，但是，我的服务器需要能够访问该目录以启动文件下载。
这是我用来完成重定向的方法：
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^(.*)$ ../ [NC]
它的工作原理就像一个魅力，但是当我的脚本尝试访问文件系统时，它自然也会被重定向。
这样做的目的是保护文件下载。用户通过保护区访问下载，下载链接类似于 http://example.com/download/superlongidhash< /a>
然后脚本会获取并读取该 URL，制定文件的实际路径并相应地发送 php 标头：
header("Content-type: application/force-download");
header("Content-Transfer-Encoding: Binary");
header("Content-length: ".filesize($path));
header("Content-disposition: attachment; filename=" . basename($path) . "");
readfile($path);
任何帮助将不胜感激:) 如果有更好的方法来执行此操作，请告诉我！
仅供参考，这一切都在 CodeIgniter 框架内
This is somewhat of a unique question that I cant seem to find the answer for anywhere! I am new to playing with htaccess files. Here's what im trying to do, let me know if this is at all possible:
I am trying to redirect when someone access a certain directory DIRECTLY, however, my server needs the ability to access the directory to initiate file downloads.
Here's what I am using to accomplish the redirect:
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^(.*)$ ../ [NC]
It works like a charm, however when my script tries to access the filesystem it naturally gets redirected as well.
The purpose of this is protected file downloads. The user's access downloads via a protected area and the download link is similar to http://example.com/download/superlongidhash
This URL is then taken and read by the script, formulates the actual path to the file and sends php header's accordingly:
header("Content-type: application/force-download");
header("Content-Transfer-Encoding: Binary");
header("Content-length: ".filesize($path));
header("Content-disposition: attachment; filename=" . basename($path) . "");
readfile($path);
Any help would be much appreciated :) If there is a better way to do this, let me know!
FYI, this is all within the CodeIgniter framework

您可以检查 http_referrer 是否适合您的网站。如果不是，您可以将用户重定向到您的主页（或您想要的任何地方）。
看看我发现的这篇关于做你想做的事情的文章。

我希望这会有所帮助。
You can check the http_referrer is the one for your site. If it's not, you redirect the user to your homepage (or wherever you want).
Take a look into this article I found about doing exactly what you want.
