我有一个网站,似乎不能从非www重定向到www。
我的Apache配置如下:
RewriteEngine On
### re-direct to www
RewriteCond %{http_host} !^www.example.com [nc]
RewriteRule ^(.*)$ http://www.example.com/$1 [r=301,nc]
我错过了什么?

如果你正在使用Apache 2.4,不需要启用重写Apache模块,你可以使用这样的东西:
# non-www to www
<If "%{HTTP_HOST} = 'domain.com'">
Redirect 301 "/" "http://www.domain.com/"
</If>

<VirtualHost *:80>
ServerAlias example.com
RedirectMatch permanent ^/(.*) http://www.example.com/$1
</VirtualHost>
这将重定向不仅域名,而且内部 pages.like…… example.com/abcd.html ==> www.example.com/abcd.html example.com/ab/cd.html ? ef = gh ==> www.example.com/ab/cd.html ? ef = gh
<VirtualHost *:80>
ServerAlias example.com
RedirectMatch permanent ^/(.*) http://www.example.com/$1
</VirtualHost>
RewriteCond %{HTTP_HOST} ^!example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
This starts with the HTTP_HOST variable, which contains just the domain name portion of the incoming URL (example.com). Assuming the domain name does not contain a www. and matches your domain name exactly, then the RewriteRule comes into play. The pattern ^(.*)$ will match everything in the REQUEST_URI, which is the resource requested in the HTTP request (foo/blah/index.html). It stores this in a back reference, which is then used to rewrite the URL with the new domain name (one that starts with www).
[NC]表示不区分大小写的模式匹配,[R=301]表示使用代码301进行外部重定向(资源永久移动),[L]停止所有进一步重写,并立即重定向。
我使用的代码是:
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
试试这个:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule ^(.*) http://www.example.com$1 [R=301]
