这里有很多类似的问题，但似乎没有一个完全相同，有什么东西让我绊倒了。我有一个特定的内部URL，mydomain.com/a-directory，我想将其转发到外部URLhttps://mailchi.mp/mydomain.com/a-directory，同时仍然将浏览器显示的URL保持为mydomain.com/a-directory.
我试过：
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^mydomain.com/a-directory$
RewriteRule ^(.*) https://mailchi.mp/mydomain.com/a-directory [P]
</IfModule>
还有：
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^a-directory$ https://mailchi.mp/mydomain.com/a-directory [P]
</IfModule>
Apache mod_proxy已安装。编辑：两者似乎都被忽视了，因为没有转发，也没有崩溃。浏览器只是说找不到该页面，因为www.httpmydomain.dom/directory不存在。
编辑：.htaccess文件包含以下内容。

RewriteCond %{HTTP_HOST} ^example.com/a-directory$ RewriteRule ^(.*) https://mailchi.mp/example.com/a-directory [P]
我已将其修改为：RewriteCond ^https://www.example.com/a-directory$
虽然代码在正确的位置(尽管它在HTTP到HTTPS重定向之前，所以您可能试图代理HTTP请求(，但您没有使用正确的指令(尽管您的问题中的第二个代码块是正确的，因为这两个域指向不同的服务器(。
以上两个条件(RewriteCond指令(都没有多大意义。上面的第二个条件在语法上无效，因为您缺少第一个(或第二个？(参数。
HTTP_HOST服务器变量包含HostHTTP请求标头的值。例如，如果您请求http://example.com/a-directory，则HTTP_HOST包含example.com。但是，如果您请求http://www.example.com/a-directory，那么HTTP_HOST将包含www.example.com。
因此，如果你正在请求http://example.com/a-directory，那么你应该使用的指令是根据你的第二个代码块：
RewriteRule ^a-directory$ https://mailchi.mp/example.com/a-directory [P]
如果您特别需要检查请求的主机，则：
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^a-directory$ https://mailchi.mp/example.com/a-directory [P]
但是，假设目标服务器允许您通过此URL代理请求(它们可能会阻止您(，那么您可能仍然需要服务器配置/virtualhost中的其他指令来正确配置反向代理。值得注意的是ProxyPassReverse指令。如果没有这一点，如果目标服务器发出HTTP重定向，则用户将被重定向离开您的域(example.com(。
