[Tutorial 9] Unclear instructions for proxy

[studersi]

Let’s have a look at a request like this and the redirect returned:

$> curl -v http://localhost/
[...]
< HTTP/1.1 302 Found
[...]

I get this:

$ curl -v http://localhost/
[...]
< HTTP/1.1 404 Not Found
[...]

It worked, once I turned on the RewriteEngine inside the VirtualHost config. But this only comes later in the tutorial and is never mentioned explicitly.
