<li>Quickly integrate content from other CMS systems, for example a company intranet.</li>
<li>Control access to protected data using WordPress’ permissions.</li>
<li>Select and remove DOM elements based on CSS selectors (like jQuery).</li>

<li>Cache the remote content.</li>

<ul>
<li>The username and password to send for <code>BASIC</code> authentication. It is recommended to not set the username and password directly in the tag, as YOUR PASSWORD WILL BE PUBLICLY VISIBLE ON YOUR WEBSITE IF THIS PLUGIN IS DISABLED, and instead use one of the other options. By order of priority, if the value matches a post <code>meta_key</code> the <code>meta_value</code> is used, if it matches a <code>site_option</code> the <code>option_value</code> is used, and if it matches a constant the constant value is used, otherwise the string data is parsed as is. The format is <code>username:password</code>.</li>

</ul>
</li>
<li><code>selector=[ CSS Selectors... ]</code>
