强制www重定向到主页，htaccess错误

Question

我有一个产品页面加载罚款，当我输入www与www（www.domain.com/product），但是当我没有，它重定向到主页（domain.com/product - > www.domain.com）。我正在使用Magento。

我一直在寻找，并试图htaccess的方法，所有的其他线程提到，但无济于事：

############################################ 
## 301 the url for SEO 
RewriteEngine On 
RewriteCond %{HTTP_HOST} !^www\.example\.com$ 
RewriteRule ^(.*)$ http://www.example.com/$1 [R=permanent,L] 

Redirect 301 /home http://www.example.com/ 
############################################ 

当我添加这个，我要么看不到任何变化或整个网站有下降500错误：重写太多。

我的主域可以使用或不使用www。这是我的htaccess的样子：

人有什么想法？

Answer 1

避免同时使用RewriteRule和Redirect。它们是不同的模块，可以相互作用，导致不寻常的副作用。

RewriteEngine On 
RewriteCond %{HTTP_HOST} !^www\.example\.com$ 
RewriteRule ^(.*)$ http://www.example.com/$1 [R=permanent,L] 

RewriteRule ^home$/[L,R=301] 

也尝试清除浏览器缓存，因为301的缓存非常积极。

您的评论后，读你原来的问题更彻底，我认为你放在WWW-规则在错误的位置。尝试将这些规则放在当前htaccess文件的顶部。
