How to block all accesses, except three IPs, to an absolute URL with htaccess?

Question

How to block all accesses, except three IPs, to an absolute URL with htaccess?

Example data: http://subdomain.example.com/url/i/want/to/block IPs: 10.10.10.10 10.10.10.11 10.10.10.12

This is my code:

RewriteCond %{REQUEST_URI} http://subdomain.example.com/url/i/want/to/block
RewriteCond %{REMOTE_ADDR} !=10.10.10.10
RewriteCond %{REMOTE_ADDR} !=10.10.10.11
RewriteCond %{REMOTE_ADDR} !=10.10.10.12
RewriteRule ^.*$ /index.php [R=302,L]

and it's not working. I'm accessing the URL with any IP.

You can't match protocol and port etc in REQUEST_URI . Have it this way:

RewriteCond %{HTTP_HOST} =subdomain.example.com
RewriteCond %{REMOTE_ADDR} !=10.10.10.10
RewriteCond %{REMOTE_ADDR} !=10.10.10.11
RewriteCond %{REMOTE_ADDR} !=10.10.10.12
RewriteRule ^url/i/want/to/block /index.php [R=302,L,NC]

Or using regex character class:

RewriteCond %{HTTP_HOST} =subdomain.example.com
RewriteCond %{REMOTE_ADDR} !^10\.10\.10\.1[0-2]$
RewriteRule ^url/i/want/to/block /index.php [R=302,L,NC]
