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

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,Allow
Deny fr开发者_Go百科om all
Allow from 123.123.123.123

Is it possible to have same type of access restriction tied to a page/document?

This will allow either someone from IP 127.0.0.1 or logged as a valid user. Stick it either in your config or .htaccess file.

    <Files learn.php>
        Satisfy any
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1

        AuthType Basic
        AuthName "private"
        AuthUserFile /var/www/phpexperts.pro/.htpasswd
        AuthGroupFile /dev/null
        Require valid-user
    </Files>

IP Alone:

    <Files learn.php>
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1
    </Files>

That definitely answers your question.

I think the directive needs to be:

Order deny,allow

for the answer above to work (at least for the IP Alone solution).

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

For a more up to date Apache 2.4 example:

<Files file.html>
    Require ip 123.123.123.123
</Files>

Here are the more in depth docs for additional options and examples: https://httpd.apache.org/docs/2.4/howto/access.html and the docs for the <Files> directive: https://httpd.apache.org/docs/2.4/mod/core.html#files

Note that <Files> can be nested inside <Directory> sections to restrict the portion of the filesystem they apply to.
