有没有办法在Apache htaccess中重写if/else？

Question

我想在我的.htaccess文件中创建的结构如下：

If (SITE A DOMAIN or SITE A SUBDOMAIN) { 
    Rewrite this specific way -> /index.php/$1 
} else { 
    Rewrite this specific way -> /directory/www/index.php/$1 
} 

下面我有我当前的代码，但它抛出500S与我的Apache错误日志抱怨：

[错误] [客户端:: 1] mod_rewrite：达到的内部重定向的最大数量。假设配置错误。如果需要，使用'RewriteOptions MaxRedirects'来增加限制。引用：

我在做什么错？谢谢！

RewriteEngine on 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond $1 !^(index\.php|blog) 

RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$ [NC,OR] 
RewriteCond %{HTTP_HOST}^example\.com$ 
RewriteRule .? - [S=1] 
RewriteRule ^(.*)$ /directory/www/index.php/$1 [L] 
RewriteRule .? - [S=1] 
RewriteRule ^(.*)$ /index.php/$1 [L]

只是使用条件而不是跳过标志（可能会引起混淆）。但它看起来像有一个重定向循环导致500.试试这个：

# If (SITE A DOMAIN or SITE A SUBDOMAIN) 
RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$ [NC,OR] 
RewriteCond %{HTTP_HOST} ^example\.com$ [NC] 
# make sure we haven't already rewritten this URI 
RewriteCond %{REQUEST_URI} !/directory/www/index.php 
# don't rewrite if the resource already exists 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
# rewrite 
RewriteRule ^(.*)$ /directory/www/index.php/$1 [L] 

# IF !(SITE A DOMAIN or SITE A SUBDOMAIN) 
RewriteCond %{HTTP_HOST} !^subdomain\.example\.com$ [NC] 
RewriteCond %{HTTP_HOST} !^example\.com$ [NC] 
# make sure we haven't already rewritten this URI 
RewriteCond %{REQUEST_URI} !/index.php 
# don't rewrite if the resource already exists 
RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 
# rewrite 
RewriteRule ^(.*)$ /index.php/$1 [L]
