403 redirect doesn't work

问题

How to force apache to redirect to a 403 error?
I've tried:

RewriteRule ^forbid/(.*)$ / [R=403,L] 

this caused 500 server error on the whole site

RewriteRule ^forbid/(.*)$ - [R=403,L] 

and

RewriteRule ^forbid/(.*)$ [R=403,L] 

these simply don't work
I have the following .htaccess file:

RewriteEngine on
RewriteRule ^(config|backup)(.*)$ - [F] [NC]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^admin/(.*)$ /admin/index.php?%{QUERY_STRING} [L,QSA] 

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !util
RewriteRule ^(.*)$ index.php?%{QUERY_STRING} [L,QSA]

Please, help me!

回答1:

Try this instead:

RewriteRule ^forbid/(.*)$ - [F]

Unless you have a RewriteBase defined that we don't see in your rules, I think you don't want the ^ before 'forbid' your expression, since it would technically start with '/'

RewriteRule ^forbid/(.*)$ - [R=403,L]
# Instead try
RewriteRule ^/forbid/(.*)$ - [R=403,L]
# Or
RewriteRule forbid/(.*)$ - [R=403,L]
