mod_rewrite重定向到文件夹

Question

I've read many posts on this subject, but for some reason none of code seems to work. If I have a domain example.com , I would like to redirect it to example.com/folder without the user knowing about the redirection.

# file: public_html/.htaccess
RewriteEngine On
RewriteRule ^/(.*)$ /folder/$1 [L]

But it doesn't send me to folder . Could someone tell me what I'm doing wrong.

Thanks

Remove leading slash and include a negative lookahead:

RewriteEngine On

RewriteCond %{THE_REQUEST} \s/+folder/ [NC]
RewriteRule ^ - [R=404,L]

RewriteRule ^((?!folder/).*)$ /folder/$1 [L,NC]
