如果根 .htaccess 文件仅包含mod_rewrite指令，则可以完全覆盖根 .htaccess 只需在/subfolder/.htaccess 中启用重写引擎即可.

If the root .htaccess file only contains mod_rewrite directives then you can completely override the root .htaccess file by simply enabling the rewrite engine in /subfolder/.htaccess.

例如:

RewriteEngine On    

PassengerAppRoot "/home/username/djangoapplication"
PassengerPython "/home/username/virtualenv/webapp/2.7/bin/python2.7"

默认情况下，默认情况下不继承mod_rewrite指令 (与其他模块不同).但是，可能已在服务器配置中专门启用了mod_rewrite继承，所以这可能行不通.

By default, mod_rewrite directives are not inherited by default (unlike other modules). However, it is possible that mod_rewrite inheritance has been specifically enabled in your server config, so this may not work.

如果这不起作用，则需要在根 .htaccess 文件的顶部创建一个例外，以防止请求/subfolder/覆盖.例如:

If this doesn't work then you would need to create an exception at the top of the root .htaccess file, that prevents requests for the /subfolder/ being overridden. For example:

RewriteRule ^subfolder - [L]

当URL以/subfolder 开头时，这会停止在 .htaccess 根文件中进行任何进一步的处理.

This stops any further processing in the root .htaccess file when the URL starts with /subfolder.
