Dear Maintainer,

While trying to use busybox httpd's proxy feature, I discovered that it
is not enabled in the Debian build [1].

Is there a reason why it is disabled? Could it be enabled? I find busybox
httpd a really simple and useful tool and would love to be able to use it
as a very basic reverse proxy in some projects.
