To address this problem, the so called <dfn>Squid + %2f hack</dfn> was implemented in the Apache FTP proxy; it is a + solution which is also used by other popular proxy servers like the <a href="http://www.squid-cache.org/">Squid Proxy Cache</a>. By + prepending <code>/%2f</code> to the path of your request, you can make + such a proxy change the FTP starting directory to <code>/</code> (instead + of the home directory).

Upon entering the password, the connection + attempt is retried, and if successful, the requested resource is + presented. The advantage of this procedure is that your browser does not + display the password in cleartext (which it would if you had used</p> + + <div class="example"><p><code> + ftp://<var>username</var>:<var>password</var>@<var>host</var>/myfile + </code></p></div> + + <p>in the first place).</p> + + <div class="note"><h3>Note</h3> + <p>The password which is transmitted in such a way is not encrypted on + its way. It travels between your browser and the Apache proxy server in + a base64-encoded cleartext string, and between the Apache proxy and the + FTP server as plaintext. You should therefore think twice before + accessing your FTP server via HTTP (or before accessing your personal + files via FTP at all!)
