[TriLUG] IE Vulnerability brings up Squid Proxy question

[Smith, Brett]

I need to Filter "Location:" headers containing the "URL:" prefix in a proxy
server.

because of this
http://secunia.com/advisories/11793/

I saw how to filter FTP and I guess I could use the same trick for URL: 

acl ftp proto FTP
acl myNet src 10.0.0.0/16
acl all src 0.0.0.0/0.0.0.0
http_access deny ftp
http_access allow mynet
http_access deny all

My ideas involve 
<--
acl url proto URL
acl location proto Location
http_access deny url
http_access deny location
-->
Any ideas?
