一些301的重定向规则

IIS 6.0 rewrite 3

1. # For ISAPI_Rewrite 3.x
   
2. RewriteCond %{HTTP:Host} ^chenyu\.me$
   
3. RewriteRule (.*) http\://www\.chenyu\.me/$1 [NC,R=301]

或：下面的规则是所有二级域名前面都会加上www，如bbs.chenyu.me，它也会加www，变成www.chenyu.me

1. # For ISAPI_Rewrite 3.x
   
2. RewriteCond %{HTTPS} (on)?
   
3. RewriteCond %{HTTP:Host} ^(?!www\.)(chenyu\.me)$ [NC]
   
4. RewriteCond %{REQUEST_URI} (.+)
   
5. RewriteRule .? http(?%1s)://www.%2%3 [R=301,L]
