301 redirect to a URL with WWW/IIS 301 redirect to a domain name starting with WWW

Prerequisites for using this method

1: You have control over the server and can operate IIS

2: You need to create two sites, one without WWW and the other with www.

 

If your website is zuogewangzhan.com, then the http://zuogewangzhan.com/vps.html was included for other reasons.

 

And what you want is that http://www.zuogewangzhan.com/vps.html is included

 

At this time, we need to redirect to 301.

In IIS, create a website named www.zuogewangzhan.com and set it to the original website directory of zuogewangzhan.com.

 

This ensures that www.zuogewangzhan.com can be accessed normally. Then set redirection in the original IIS Site of zuogewangzhan.com

Redirect to http://www.zuogewangzhan.com $ q note, followed by $ Q to ensure that the parameters after the URL can also be passed correctly (that is, access to ingress)
