Try to jump the ISAPIRewrite statement without the www domain name to the ISAPIRewrite statement with the www domain name

I want to write ISAPIRewrite without the www domain name to the domain name with the www domain name. I want to use the dig (. *) RewriteRule command to jump the ISAPI Rewrite method without the www domain name to the domain name with the www domain name.
I want to jump to http://www.abc.com/zb/

Note that the path after the domain name must also be included.

RewriteCond Host: ^ abc \. com (.*)
RewriteRule (. *) http \: // www \. abc \. com $1 [I, RP]

What's wrong with me?

RewriteEngine on
RewriteCond % {http_host} ^ abc.com [NC]
RewriteRule ^ (. *) $ http://www.abc.com/#1 [L, R = 301]

Reference:

It doesn't matter if it's not a directory.
Example:

RewriteCond % {HTTP_HOST} ^ 162100.com [NC]
RewriteRule ^ (. *) $ http://www.162100.com/#1 [L, R = 301]

This method is incorrect.
