"As I mentioned in one of the above posts, nothing gets in my tweaked cache (I use Nav, remember?).
However, just to get that cache issue out of the way, and because I respect your opinion, I did what you said."
I'll bet you didn't close your browser, start new browser THEN go to grc and test anon proxy in new browser.
"I really wish someone else would try it out, just to see."
I did and can repeat your problem. When you first "Test My Shields!" grc remembers that IP for additional tests (proxy or no proxy), maybe with enviornmental variable UNIQUE_ID. Looks like a grc bug. So, to test from another IP, i.e. your anon proxy, you need to test in browser with no previous grc history.
"Hey wait a minute! I just noticed that the ShieldsUp test site is https.
Might that mean something???"
As I mentioned earlier in this thread (remember?):
"ShieldsUp initial page is a https (SSL) connection. Your proxy must support https for it to work. One way to test proxy https support is to attempt connect to https URL like [url]https://www.mail2web.com/cgi-bin/login.asp?lid=0&il=0[/url] "
