我有两个顶级域名指向我的Drupal安装，abc.com和xyz.com。
我想强制所有页面使用abc.com，除了一页（节点），它应该始终使用xyz.com。
我尝试了一堆不同的.htaccess，似乎都没有用。这是我得到的最接近的：
# Redirect abc.com/path/to/my/page to xyz.com/path/to/my/page
RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com$ [NC]
RewriteRule ^path/to/my/page$ http://www.xyz.com$1 [R,L,NC]
# Redirect xyz.com to www.abc.com
RewriteCond %{HTTP_HOST} ^(www\.)?xyz\.com$ [NC]
RewriteRule ^ http://www.abc.com%{REQUEST_URI} [R,L]
以上适用于整个站点重定向，但是当你转到abc.com/path/to/my/page时，它会重定向到主页abc.com。我也试过这个：
# Redirect abc.com/path/to/my/page to xyz.com/path/to/my/page
RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com$ [NC]
RewriteRule ^path/to/my/page$ http://www.xyz.com/path/to/my/page [R,L,NC]
但是这只是给了我一个关于xyz.com/path/to/my/page重定向过多的错误。
有什么想法吗？我不确定我的.htaccess代码是否错误，或者它是否与Drupal的干净URL功能有关，或者是什么。

您的代码会生成一个循环。 abc.com/path/to/my/page重定向到xyz.com/path/to/my/page，但所有xyz网址都重定向到abc.com，因此会一遍又一遍地重定向回abc.com/path/to/my/page。
# Redirect abc.com/path/to/my/page to xyz.com/path/to/my/page
RewriteCond %{HTTP_HOST} ^(www\.)?abc\.com$ [NC]
RewriteRule ^(path/to/my/page)$ http://www.xyz.com/$1 [R=302,L,NC]
# Redirect xyz.com to www.abc.com (except for /path/to/page)
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{REQUEST_URI} !^/path/to/my/page$ [NC]
RewriteCond %{HTTP_HOST} ^(www\.)?xyz\.com$ [NC]
RewriteRule ^ http://www.abc.com%{REQUEST_URI} [R=302,L]
您的第一个代码中的规则不正确，将abc.com/path/to/my/page重定向到abc.com/（并且没有创建循环）。
RewriteRule ^path/to/my/page$ http://www.xyz.com$1 [R,L,NC]
这是因为$ 1对第一对括号的引用，但你没有。其次，您需要在其前面添加/，否则它会重定向到xyz.compath/to/my/page
