allow file_get_contents() / curl() from specified domains only
<p>I'm building a script that uses file_get_contents to grab data from my website, which will be distributed among my clients. I don't want everyone to be able to grab this data, and therefore I would like the page with the data to be protected, so that only file_get_contents requests from specific domains are allowed.</p>

<p>Does anyone know how I can achieve this?</p>
