1、首先需要为服务器配置好伪静态(Windows:ISAPI_Rewrite,Linux:mod_rewrite)

2、上传伪静态规则到站点根目录下就可以了。

httpd.ini

[ISAPI_Rewrite]

# 3600 = 1 hour

CacheClockRate 3600

RepeatLimit 32

# Protect httpd.ini and httpd.parse.errors files

# from accessing through HTTP

RewriteCond Host: ^domain\.com$

RewriteRule (.*) http\://www\.domain\.com$1 [RP,I]

.htaccess

RewriteEngine On

RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]

RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
