<para>This option instructs FreeBSD to use the HTTP
protocol (like a web browser) to connect to a proxy
for all FTP operations. The proxy will translate
the requests and send them to the FTP server.
This allows the user to pass through firewalls
that do not allow FTP at all, but offer a HTTP
proxy.
In this case, you have to specify the proxy in
addition to the FTP server.</para>
