-/**
- * Adds Proxy support to the WordPress HTTP API.
- *
- * There are caveats to proxy support. It requires that defines be made in the wp-config.php file to
- * enable proxy support. There are also a few filters that plugins can hook into for some of the
- * constants.
- *
- * Please note that only BASIC authentication is supported by most transports.
- * cURL and the PHP HTTP Extension MAY support more methods (such as NTLM authentication) depending on your environment.
- *
- * The constants are as follows:
- * <ol>
- * <li>WP_PROXY_HOST - Enable proxy support and host for connecting.</li>
- * <li>WP_PROXY_PORT - Proxy port for connection. No default, must be defined.</li>
- * <li>WP_PROXY_USERNAME - Proxy username, if it requires authentication.</li>
- * <li>WP_PROXY_PASSWORD - Proxy password, if it requires authentication.</li>
- * <li>WP_PROXY_BYPASS_HOSTS - Will prevent the hosts in this list from going through the proxy.
- * You do not need to have localhost and the blog host in this list, because they will not be passed
- * through the proxy. The list should be presented in a comma separated list</li>
- * </ol>
- *
- * An example can be as seen below.
- * <code>
- * define('WP_PROXY_HOST', '192.168.84.101');
- * define('WP_PROXY_PORT', '8080');
- * define('WP_PROXY_BYPASS_HOSTS', 'localhost, www.example.com');
