preferred proxy tester?

[toast]

i know there's 101 sites out there
to test if your proxy is working or detectable,
but what's your preferred one?

there's one site that keeps saying it can detect a proxy
(when the rest can't), so my one worry is that neo will pick up on it.
(total paranoid over here, if you can't tell)


although neo might be super outdated in that sense...
regardless, what works for you?

ipnow.org ([Only registered and activated users can see links]) reports as "anonymous/no proxy" when I manipulate.

[Only registered and activated users can see links] is usually spot on.

thanks Victoria and Skarl!
