htaccess仅在HTTP引荐来源网址不等于某值时才重定向 [英] htaccess Redirect only if the HTTP referrer does NOT equal something

问题描述

我有以下规则可以将中文用户重定向到网站的中文版本:

I have the following rules working to redirect chinese users to the chinese language version of the site:

  RewriteCond %{HTTP:Accept-Language} ^zh [NC]
  RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
  RewriteRule ^(.*)$ http://ch.example.com/$1 [L,R=301]

  RewriteCond %{HTTP:Accept-Language} ^zh [NC]
  RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
  RewriteRule ^(.*)$ http://ch.example.com/$1 [L,R=301]

这很好.

但是，应该有一个链接可以将其带回该网站的英语版本，该站点只是普通域名(www.example.com).

However, there is a link that is supposed to take them back to the english language version of the site, which is just the normal domain (www.example.com).

但这只是将它们直接重定向回中文站点，因为它符合规则.因此，我需要这样做，以便仅当引荐人不是ch.example.com时才触发上述规则.

But this just redirects them straight back to the chinese site, because it matches the rules. So I need to make it so the above rules are trigger ONLY if the referer is NOT ch.example.com.

我尝试过这样的事情:

  RewriteCond %{HTTP:Accept-Language} ^zh [NC]
  RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
  RewriteCond %{HTTP_REFERER} !^http?://ch\.example\.com/ [nc]
  RewriteRule ^(.*)$ http://ch.example.com/$1 [L,R=301]

但这是行不通的.

推荐答案

当用户在英语网站上查看第二页时，它将重定向到中文.更好的方法是设置一个cookie，然后检查它:

What about when the user views their second page on the English site, it will redirect to Chinese. A better method is to set a cookie and then check it:
