如何在 OpenShift 上正确地将 www 重定向到 no-www？

Question

我有一个在 730ne.cz 和 www.730ne.cz 上运行的 OpenShift Python 应用程序，我希望 www 版本重定向到非 www。

我添加了具有以下内容的 wsgi/.htaccess：

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

但这也以无限重定向循环结束http://www.730ne.cz/application/application/application/application...

所以我尝试了以下方法：

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/ [R=301,L]

还有：

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www.730ne.cz [NC]
RewriteRule ^(.*)$ http://730ne.cz/ [R=301,L]

还有：

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www.730ne.cz
RewriteRule ^(.*)$ http://730ne.cz/ [R=301,L]

但我得到的只是：

$ LANG=C wget http://www.730ne.cz/
--2015-03-12 21:40:13--  http://www.730ne.cz/

我做错了什么？如何正确执行此操作？

我在 OpenShift 上托管的 WordPress blog 也遇到了同样的问题，我使用以下 .htaccess 规则修复了它：

RewriteEngine On
RewriteBase /

# www to non-www
RewriteCond %{HTTP_HOST} ^www.subinsb.com$
RewriteRule (.*) http://subinsb.com:80/$1 [R=301,L]
