Hi Bruce,

Well I don't know about the general situation but in my case Chello
could very easily tell that I am using a proxy server.

If I run this whois web interface:
http://www.leader.ru/secure/who.html

...I receive this output:
Remote address 203.109.252.15
SQUID-like proxy servers detected 2
Nearest client for this type of proxy 192.168.100.11
Name of the nearest proxy Proxy+
Type of the nearest proxy v2.30 http://www.proxyplus.cz
The client's address we got 192.168.100.11
You're probably sitting on the LAN connected to the NAT/Proxy
NAT address we got p57-tnt2.akl.ihug.co.nz
Browser MSIE v5.X
OS Windows NT

Thus you can clearly see I am running Proxy+, version 2.30, and you can
also see the private IP address of the client I am sending this from!
Personally I'd like to be able to block this information but I can't
figure out how, even using a firewall (not because I'm not allowed to
use a proxy server but for the simple fact that advertising the software
and version you are using opens you up to program- and version-specific
exploits).

Regards,
Adam

And they can tell ... how?
