.htaccess: how to restrict access to a single file by IP?

Question

I\'ve look all over, but keeps running into same info that talks about directory level IP restriction, which usually looks something like this:

Order Deny,A         


        

Answer 1

Mod-rewrite based solution :

RewriteEngine on

RewriteCond %{REMOTE_ADDR} !^Y\.O\.U\.R\.IP$
RewriteRule ^file\.php$ - [F,L]

The rewriteRule above will deny all requests to file.php if client ip does not match the ip address in the RewriteCond's pattern
