Unless you specifically set up the httpd.conf to allow proxy-CONNECT
then it's likely that you are not an open proxy.  The "success" error
code can be misleading, see
<http://httpd.apache.org/docs/1.3/misc/FAQ.html#proxyscan>.  You really
have to go out of your way to setup Apache as an open proxy, it will
most certainly not do that by default.  So if you are using a stock
config you have nothing to worry about.
