CFHTTP requests don't really differ significantly from HTTP requests made by
a browser. However, your browser may be configured to use a proxy, while
CFHTTP wouldn't know anything about that.

For testing, I'd recommend you use a recording proxy, or just download
something like wget and use that to test connectivity from your server
console.
