PHP: an example where allow_url_include is a good idea?
<p>I just noticed a PHP config parameter called <a href="http://www.php.net/manual/en/filesystem.configuration.php#ini.allow-url-include" rel="nofollow"><code>allow_url_include</code></a>, which allows you to <code>include</code> a PHP file <em>hosted elsewhere</em> as you would a locally.  This seems like a bad idea, but <em>"why is this bad"</em> is too easy a question.</p>

<p>So, my question: When would this actually be a good option?  When it would actually be the best solution to some problem?</p>
