This is a problem with Squid, as I was able to replicate the same bypassing
with Opera.

Subject: a litle bypass with IE




 hello  im not a expert in this area, but i work in a intranet that haves
the Squid/2.3.STABLE5 filtring all access's to the internet..   so i don't
have access to the internet directaly, but i know that this proxy allow
access to especific web sites.. so, in the past if i us this:
http://url@website_allowed.pt -> the vuln that is already discovered... i
have access to the website that i want...  but in this days, this vuln is
now fixed so...  in my test's i found this way to pass this proxy, using:
http://@@website_allowed.pt@my_url -> now i have access...  using @@url.pt@
i can bypass the proxy and access the internet, i don't know how faur, this
could go!!  so i don't know if this is a bug from IE or just a simple bug
from Squid.. ??? can anyone tell what we have in hands ?  PS: sorry my
